How to unlock iOS 4.2.1 on iPhone 3G and iPhone 3GS with ultrasn0w
The ultrasn0w unlock for iOS 4.2.1 has been released and it works to unlock iPhone 3GS and iPhone 3G running iOS 4.2.1 on basebands 04.26.08, 05.11.07, 05.12.01, 05.13.04 in addition to 05.14 and 05.15 via updating to 06.15.00 iPad baseband. Using the ultrasn0w unlock isn’t complicated, but it’s a multi-step procedure that carries a few risks and first requires you to jailbreak your iPhone. Before you get started with the unlock, you need to consider the following:
Important notes about iOS 4.2.1 unlock on iPhone 3GS and iPhone 3G
- Unlocking your iPhone voids your warranty from Apple
- For basebands 05.14 and 05.15 this iOS 4.2.1 unlock requires you to update to baseband 06.15 from iPad 3.2.2 firmware onto your iPhone, this can not be reversed
- You can not downgrade from baseband 06.15 (the iPad baseband), and you will no longer be able to restore to stock firmware. This means you will forever need to use your custom saved IPSW files!
- And finally, directly from the iPhone Dev Team: “iPhone3GS users with old bootroms who want to go to iOS 4.2.1 should not use PwnageTool! Update to stock iOS 4.2.1 first (through iTunes) then use redsn0w 0.9.6b5 to update your baseband.”
It is important that you understand and accept these risks before proceeding.
How to unlock iOS 4.2.1 on iPhone 3GS and iPhone 3G using ultrasn0w
If you have older baseband, you can go straight to using ultrasn0w. You can update to iOS 4.2.1 from iTunes but this will update your baseband and require the use of the iPad firmware. Here are the steps to unlock, the process is basically the same with Pwnage or redsn0w:
- If you are using PwnageTool, Basebands 05.14 and 05.15 need to download this iPad IPSW file in addition to PwnageTool 4.1.3 Unlock Edition (Mac)
- You can also just download redsn0w 0.9.6b5 for Mac and Windows
- If using PwnageTool to create a new custom IPSW, use the aforementioned IPSW download (yes its for iPad).
- If using redsn0w 0.9.6b5, the app will automatically download the iPad IPSW for you
- Jailbreak your iPhone 3G or iPhone 3GS, pointing it at the newly created custom IPSW
- After your iPhone has been jailbroken, reboot the device and then launch Cydia
- Tap on “Manage” and then tap “Sources”
- Tap to “Edit” and then “Add” a repository, and then type the following: http://repo666.ultrasn0w.com
- After the repository has been added, you can search for “ultrasn0w” and download version 1.2
- Download and install ultrasn0w 1.2, this will automatically unlock your iPhone 3GS and iPhone 3G
- Restart your iPhone and enjoy your unlock
The process of jailbreaking and unlocking iPhones usually sounds more confusing than it is, just follow instructions carefully. The main problem with this unlock method is that certain baseband versions require the use of an iPad baseband which can not be reversed, this marks your iPhone in an obvious manner to Apple and this is why it voids your warranty with them. Jailbreaking is not illegal but it is frowned upon by Apple, however the difference between a standard jailbreak and this particular unlock is that jailbreaking is reversible, and this unlock is permanent.
Update: the iPhone Dev Team forgot to include the proper bundle for iPhone 3GS users on 4.1 with PwnageTool 4.1.3, but you can fix it rather easily. Here are their comments on the matter:
There’s an error in the bundle for the iPhone3GS 4.1 that prevents the new baseband from being used. If you know your way around OSX, please download the fixed bundle, and unzip it if Safari hasn’t already done so. Then “Show Package Contents” of PwnageTool.app, navigate to Contents->Resources->FirmwareBundles and drop it there. Otherwise, please wait for the updated PwnageTool, or the OSX version of redsn0w coming soon.
Update 2: The redsn0w 0.9.6b5 download is now available for Windows and Mac, it’s an easier method to perform the jailbreak and unlock for many.

Okay, I got my iPhone 3G working enough to make phone calls.
I re-installed ultrasn0w via Cydia.
Re-booted and put in my T-mobile SIM which was then recognized.
However, I can’t get the internet portion to work. The iPhone should be able to work on T-mobile’s EDGE network which is much slower than 3G, but no internet.
Thanks for or all the help…. I successfully unlock my IP 3g can now use my mobile sim… Thanks for the entire team
SO I DID EVERYTHING WITH ULTRASN0W AND MY IPHONE JUST SAYS “No SIM” whenever I try to put in my T-Mobile SIM card in it. Anyone know why this happens? I toook my T-Mobile SIM out of my blackberry and tried to put it in my “unlocked” iphone and it does not work :( I have 4.2.1 and 06.15.00
I have the same problem.
I have 4.2.1 and 06.15.00 on my iPhone 3G, and I inserted my T-mobile SIM card, and the SIM is not recognized.
Did you ever get you iphone working? I am having the same issue…
No, I never got my iPhone working.
I have two T-mobile SIM cards – one for prepaid phone only and one for the unlimited 4G service for my smartphone.
iPhone reports No Carrier
Hi, I have an iPhone 3g 8GB with 4.2.1 and 06.15.00 bb and it is not JB. Can I JB it and then unlock my phone to read the SIM(carrier) ?
Hi, i have jailbreak 3g for 4.2.1 bb 5.13.04 using redsn0w and it works great but have problem with carrier. i have installed ultrasn0w but still cannot recognized my sim. the same sim when i used 3.1.3 i dont’ really remember coz i just decided to click update on itunes and turns out everything is lost. everything works perfectly except the carrier. i tried to update the baseband using redsn0w. but redsn0w just exit out when i checked the bb and trying to reboot. but it exit leaving my iphone unable to switch on. so i do it again without bb checked but i still have no network list. please can you help?

hey guys.. how about if my iPhone 3g has already jailbroken and i want to get it back to normal can i restore it in iTunes???
Yes. Just click restore and when then choose fresh/new iphone.
redsn0w crashes everytime it goes to load ipad ipsw???
You are probably using the wrong IPSW or the improper version of the app for your iOS version. Use newer software appropriate for your device.
The instructions confuse me…it says “newly created ispw” when using Pwnage…what is the newly created ispw?
I have a unlock iPhone 3GS and I cnt send and receive picture mail. Please help me… How can I get faster Internet speed?
You can get faster internet speeds by using a faster network.
Done. worked fine. thanx.

Just a bit confused as to whether using this iPad firmware, I will be able to restore these contacts etc to my iPhone after unlocking? Just not understanding ‘custom ISPW files’ and ‘will not be able to restore stock firmware’. Thanks.

3G 4.2.1 Ultrasn0w 1.2.3 DID NOT WORK AT FIRST…
I may have missed other comments, but I just got my phone working and need to put this story out here.
Just as I said, this method did not work and my phone was not getting signal, so I started over as follows:
– Use iTunes 10.2.2, restore iPhone to legit ipsw 4.2.1, it may fail, that’s fine, it cleared out iTunes restore errors and got my restoration process working again for some reason
– Use PwnageTool 4.2 to build a custom image of 4.2.1, but the trick is, uncheck everything in the General preferences. Yes, uncheck the Activate box. If you’re unlocking, you don’t want this. I didn’t need to use PwnageTool to put the phone into DFU for me, but I don’t think it matters if you do.
– Use iTunes to restore to your custom 4.2.1 ipsw
– When it reboots, set up the iphone as a brand new device, don’t recover from a backup.
– In Settings/Network, disable 3g AND cell data.
– Connect to a wifi network and run Cydia.
– Allow Cydia to do full updates and reboot you
– Run Cydia again and search for Ultrasn0w (at the time of this writing, the current version is 1.2.3)
– Take out SIM during reboot, and plug it in when it’s done.
– You should get a pop-up saying activation complete.
I hope this saves someone else the hours I’ll never get back failing at this, lol!
Since no one here actually seems to care about the people who ask questions, allow me to answer your question.
There is no unlock for you iphone, why? Like you pointed out: because of your firmware baseband. Why? Sorry, dont know the answer for that one. It seems it would have some special attribute which no one has been able to crack yet, so sorry.
On the other hand, there is a method of sorts. This would involve changing the iphone’s firmware baseband for that one of the ipad. This means that if and whenever you hook your iphone to itunes it will think its an ipad. That means you CANNOT restore your iphone if anything goes wrong, which means you loose your iphone for good.
Also, should it happen to work, you might loose several functions, including the GPS (maps app), or you might not, just like you might.
Personally I have not used this method, I have no intention nor desire to try it and I advice against it, just how I was advised against it myself.
Hope that helps, or at least answers your question.
I have a 3G iphone running 4.2.1 with 05.15.04 firmware that I have jailbroken and am trying to unlock. I tried the ultrasnow, to no avail, but just read here that it might be because of my firmware.
Any idea how to unlock it?
Also, it says above that I will forever need my custom saved IPSW files if I do this… how do I save these? Is this a bad idea? I really just want to use another carrier… any recommendations?
My iPhone 3GS is running on iOS 4.2.1 BaseBand 05.15.04. Is there ANY way to unlock it for any service carrier without changing the BaseBand to the iPad’s?

what the the benefits of unlocking my phone?
use with any carrier any where in the world that uses GSM

Hi, I bought iPhone 4 IOS 4.2.1. from USA. I found phone is lock and can not use in Singpaore. How to unlock and who can unlock. Anyone one help me on this?
iPhone 4 doesn’t have a reliable untethered jailbreak yet.
One is very close to being released though.
I haven’t heard much about unlocking the iPhone 4 unfortunately.

I have got a iPhone 3G 4.2.1 baseband 5.15 which I have Jailbroken with redsn0w 0.9.6b5. I have had to manually download the ipad baseband 3.2.2 and select it as Redsnow won’t automatically download it as stated in the instructions. I have followed the instructions but I can’t get it to install iPad baseband 3.2.2. Whenever I try Redsnow stops at “Please wait while your device is being processed.” The phone then powers on and I’m still left with baseband 5.15.
Anyone know how to fix this?
I REALLY screwed up. I have an iPhone 3G and I recently updated it to ios 4.2.1 and then went through the redsn0w mac_0.9.6b6 jailbreak and then the ultrasn0w 1.2 unlock.
I DID upgrade to the new bandwidth. Somewhere along the way I lost the phone icon on the Springboard. I decided that it would be easier to start with a clean slate and reload the firmware so I could try again… bad idea!
Now I have an iphone that always shows the hook up to iTunes icon and I have tried to reload using iTunes and redsn0w to no avail.
Did I fry my phone?
i had the same problem. after 48 hours of research this is what worked for me. TESTED AND WORKING

I have the iphone 3g, I am currently running on 3.1.3 with 5.13.04. I am unlocked, because I am using TMobile on the phone. I want to upgrade through itunes to 4.2. Can I follow all of the simple instructions to unlock again after I upgrade to 4.2? I currently have Cydia installed on my phone.
I have a 3G locked iphone with 04.26.08 baseband on version 3.1.2.
I would like to upgrade to 4.2.1, and since dev-team said I shouldn’t upgrade to the iPad baseband, my only option is to use a custom ipsw file (which is already jailbreaked), and then simply install ultrasn0w.
If I’m right about this, can anyone help me finding that ipsw file? because all the ipsw files I found are already using the new iPad baseband (06.15)
I have a 3G 8mb bb 04.26.08 iOS 3.0

im on 4.1 BB 05.14. but without a unlock, though i need one.
Correct me if i am not right.
I download the iPad 3.2.2 IPSW, select the ipad in pwnagetool, create a custom ipad firmware and try to restore in itunes? This doesnt work for me at all.
Probably I am wrong though.
Which FW needs to be on the phone to unlock&jailbreak and which fw do I need to use in pwnagetool?
I am getting the message connect to iTunes and nothing is happening. Neither it is restoring and this not happens.. I am a MAC user!
GUIDE.. I dont ant to throw this in rubbish bin.. using like iPOD with 4.1 was better..

Those people who are not able to restore 3G after getting stuck with jailbreaking/unlock 4.2.1 with bb 06.15
1) restore iPhone back to 3.1.3, error would show up 1015, ignore it
2) download recboot (www.mediafire.com/?nn1kzmmwkjg) & unzip it, install setup file libusb-win32-filter-bin-0.1.12.2.exe (Win7 rgt-click properties-run as admin and winxp sp3 compatibility mode).
3) run Exit.bat – iPhone will restart
4) use redsn0w-win_0.9.4 & point it to 3.1.2 ipsw
5) iPhone will jailbreak to 3.1.3 bb 06.15
6) iPhones with working wifi can goto Cydia and install unltrasn0w 1.2
iPhone without wifi
1) download SetupiPhoneBrowser.1.93.exe – http://code.google.com/p/iphonebrowser/downloads/list
2) download ultrasn0w 1.2 .deb – http://www.megaupload.com/?d=UJKGUM4A
3) Open iPhoneBrowser – (Create folders Cydia and AutoInstall right after Media) in var/root/Media/Cydia/AutoInstall
4) Drag & drop ultrasn0w and mobile subrate insiide AutoInstall folder
5) Restart iPhone twice, carrier will come up and enjoy :)
I tried doing the recboot and it did not work. I would get into recovery mode and install the libusb-win32-filter-bin-0.1.12.2.exe but when i tried to open exit.bat it would never pop up or do anything. Any suggestions?

hi, after i unlocked my 3gs iphone i have problem with my gps – it can’t connect to any satelite and another problem is that the battery is going empty very fast.

There are reports everywhere that various antennas on the 3G and 3GS no longer work after the 4.2.1 update. This goes for both unlocked and legit iPhones. Someone plz confirm this…cuz my jailbroken and unlocked 3GS’ Bluetooth, texting and GPS are all out of whack!
Anyone experience abnormal slow edge speeds? I called t mobile and they said everything was fine on their side with my iphone and the speed should be higher. im getting like 2-6 kB/s on speedtest apps

I have this little problem i use pwnagetool and i finally get the unlock with cydia/ ultrasnow, but my Iphone 3G i can use a wallpaper, i just have this black background i try using winterboard and nothing, and i can see the bar i used to have for the respring, wi-fi, 3g, etc. bar that came with the jailbreak… oh! and i have no multitasking. It’s great that i can finally have mi iphone working as a phone back but, i miss the multasking, the option bar and the colorfull background.

Hej…everyone… it is great! Works perfect! Thanks to dev team and OSXDaily :)
Need help!!! My redsnow is stuck at waiting for reboot. Im having 3G with bb 05.15… What should I do?
I’m having the same issue as well; just sits at the “waiting for reboot” part. Anyone know what’s going on and anyway to work around it?
right click, and select properties, then select the ‘compatibilty’ tab, and click run as ‘service pack sp3 windows xp’ (or something like that’, then at the bottom tick the box beside run as adminstrator. Hope it helps, works for most.
works perfct !!!!!!!!!! thks
Have a 3G running baseband 04.26.08 what’s the crack with unlocking that? =s it only talks of higher basebands. Want it in 4.2 if possible?
Hi, I’m trying to unlock my iPhone 3G 4.2.1 using redsn0w 0.9.6b4 and everything looked smooth. I was able to jailbreak sucessfully and then followed the instructions given here to unlock using ultrasn0w that is download the ultrasn0w 1.2 and install using cydia on my iPhone. The article says once the ultrasn0w installation is complete, iPhone will be automatically unlocked. But I’m not sure if my phone is indeed unlocked. I’m saying this because after putting a different AT&T SIM (pre-paid) in my iPhone, I dont see ATT displayed on my phone nor I’m able to make any calls. Some one please help….Thanks much in advance.
Your iPhone is unlocked. I have prepaid AT&T Sim and it doesn’t work on mine either. When I put prepaid Tmobile, it worked like a charm.
Hey, It’s working now. I just went to cydia app, located my resource http://repo666.ultrasn0w.com and re-installed it using modify option. The phone started working with my ATT pre-paid. However, when I rebooted it again did not work and I had to repeat the same procedure above to have it working…not sure this is how it is
ultrasn0w doesn’t work
hey im just wondering i have a 3G to and i just did the same thing and its doing what yours did… what can i do its not reading any sim card that i put in it just keeps saying searching do u know what i can do to make it work again i dont even care if it gets unlocked now
I tried putting in my prepaid Tmobile sim and it didn’t work. Is there anything I can do or is my phone a dud now?
alright. i understand the consequence now. i’m diving in to update the iphone 3g baseband to 06.15.00. no matter what happens afterward, i will remember the happiness when using the old baseband and old ipsw.
Iphone 3G , but now I want add soft new can not install.
Please help me
hej, i have iPhone 3G iOS 4.1 (BB 05.14.02) should i upgrade to iOS 4.2 from iTunes and when i use redsn0W should i poin to IPSW for iPAD? can you please write stp by step guide HOW TO DO! Thanks!
Jailbreak with iPhone ipsw and redsn0w fetches iPad baseband for you nothing to do with your end.
i tried to use the ipad ipsw and my iphone doesnt reboot it just stops and doesnt jailbreak. I am using redsn0w. Can you help?
Make sure you are using redsn0w 0.9.6b5
You can download it here:
Yeah, im sure! I tried to unplug than plug the USB but still doesnt works! What about now?
Something tells me I have to select “Ipad” instead of “Iphone 3g” Right?
No, you select your standard iOS device (say, an iPhone) and then the next step will ask if you want to use the iPad firmware. Remember, using iPad baseband on the iPhone is irreversible, so do so at your own risk.
Am a little confused, my baseband is 5.14.02. Can I use this method to unlock the phone by first doing the jailbreak over again? since I used redsnow to do the jailbreak the last time. I tried installing the ultrasnow 1.2 but it hangs the phone in its current state. Thanks alot..
Yes, undo your existing jailbreak then start over again with Pwnage, then you can use ultrasn0w
Ok, been trying to do just dat, it tells me me “wrong firmware bundle selected” I downloaded the ipsw from the dev team directly and the unlock version of Pwnage tool from them too. What am I do wrong? Thanks
Do you already have an unlock?
If you dont have an unlock, just restore your iPhone from iTunes to undo the jailbreak, then proceed as usual with Pwnage (redsn0w is easier IMO).
Thanks for your help. Did a restore with Itunes and then the jailbreak all over again but this time flashed the baseband. after installing Ultrasn0w it picked up the network like magic. Hope I don’t regret upgrading to the Ipad baseband…. Much appreciated.
What if I already jailbroken with limera and have cydia on my iphone? I have iphone 3gs BB 05.14.02 what should I do?
If you just want to jailbreak your iPhone then you can upgrade to 4.2.1 and then use PwnageTool (without iPad part) to jailbreak 4.2.1 no problem.
The iPad part only matters if you are on 5.14 and you want to unlock.
Like souns, I have 3GS JB@4.0.1 and don’t want
To lose or reinstall all my cydia
yes all you need to do is go to cydia, go to manage, go to edit then add, then type this in : repo666.ultrasn0w.com then click the app and click install.
Hope this helps
I am so happy with my 3GS JB @4.0.1
Comex JB was easy. I tried getting
Into DFU mode before @3.x and
it never got there. I want to update
But smell trouble
I have iphone 3gs firmware 3.1.3 with baseband 5.12. This thing describes that it can unlock 3gs operating 4.1.2 with baseband 5.12. The confusing thing to me is, it says “If you have older baseband, you can go straight to using ultrasn0w. You can update to iOS 4.2.1 from iTunes but this will update your baseband and require the use of the iPad firmware.” <– this would mean that i would be get stock 4.2.1 from itunes which will upgrade to a higher baseband and then have to upgrade to 6.15 right? If thats the case i understand the rest. But i do not want to update baseband. How do i install 4.2.1 into my iphone without it affecting my baseband so can be like in the description " it works to unlock iPhone 3GS and iPhone 3G running iOS 4.2.1 on basebands 04.26.08, 05.11.07, 05.12.01, 05.13.04"
I dont understand how to get 4.2.1 installed without it updating the baseband.
did u manage to do this? me too having the same confusions
uNLOCK UR PHONE FIRST
Then u can search for custom 4.2.1 ipsw file on google for unlocked phone. You will also find guides to do that.
BUT do not update via itunes
[…] you are not sure what to do, you can learn how to unlock iOS 4.2.1 for iPhone 3GS and iPhone 3G with ultrasn0w, the unlock does carry some risks for certain baseband versions, since the iPad firmware based […]
