If you’ve maintained old iPhone baseband in order to utilize carrier unlocks, you’ll be pleased to know that you can now upgrade to iOS 5.0.1 and jailbreak untethered the iPhone while preserving the unlockable baseband. The procedure is done by using the newest version of PwnageTool 5.0.1, and if you’re familiar with past versions of pwnage then you should be right at home, but nonetheless we will walk through the entire process.

Note: Only need a jailbreak? If you don’t need a carrier unlock, use this guide to jailbreak iOS 5.0.1 untethered with redsn0w, it’s faster and doesn’t include the baseband preservation.

Before proceeding, make sure you meet the following requirements:

  • iPhone 4 or iPhone 3GS with preserved and unlockable baseband: 01.59.00, 04.26.08, 05.11.07, 05.13.04, 06.15.00
  • iOS 5.0.1 IPSW – optional, depending on if you already have it stored locally or not
  • iTunes 10.5.2
  • PwnageTool 5.0.1 – download now

Assuming you meet all those requirements and you understand the risks, continue on. Read carefully or else you can accidentally update your baseband and lose your unlock.

Jailbreak iPhone with iOS 5.0.1 while Preserving Baseband Unlock

  • Launch PwnageTool 5.0.1 and select your iPhone model, then click the next arrow
  • Let PwnageTool search for firmware (or you can download iOS 5.0.1 firmware manually), select it and click the Next arrow again
  • Click “Yes” when asked if you want to save the custom IPSW file to the desktop, and click yes/no depending on your activation
  • Let PwnageTool build the custom IPSW, enter the administrator password when asked
  • Now connect the iPhone to the computer and place it into DFU mode: Hold power button for 3 seconds, continue holding Power button and also hold the Home button for 10 seconds, release Power button but continue to hold Home button for another 15 seconds
  • When DFU is confirmed, quit out of PwnageTool and launch iTunes
  • Hold the Option key and click on “Restore” and select the custom firmware created by PwnageTool, located on the desktop
  • iTunes will now restore the iPhone to the custom iOS 5.0.1 build, simultaneously jailbreaking the phone and also preserving the unlockable baseband
  • After the device has been jailbroken and booted up, launch Cydia and download Ultrasn0w 1.2.5 to unlock the iPhone

The unlocked iPhone should now be good to use on another carrier. If you have trouble activating, use the original activated SIM card briefly to pass through activation, or run the newest version of redsn0w on top.

    What a lame approach to life. So instead of creating things for yourself like the Linux crowd does, which you are unable apparently to do, you “jailbreak” your iPads and phones so that you can do what, tether or something? Meanwhile whatever hacker devised the jailbreak has given himself backdoors to steal your private information like they do at Best Buy. This practice of jailbreaking just screams ignorance, stupidity and lameness, it advertises these in fact.

      Talk to apple about this one. And please do research before your start saying things to demotivate apple’s customer base .. It surely does not effect you in any way .. (unless your a developer) ..

      Im sorry to know that some* people just hate this so much.
      Cheers.

  8. jessie says:

    when I downloaded PwnageTool 5.0.1 I could not launch it. “The archive is either in unknown format or damaged”

    Well .. Personally .. As a member of all jailbreakers world wide .. I just wish there was an easier way to unlock your $300 to $1000 iPhone .. but unfortunately all of us “thiefs” have no other options than to deal with (baseband issues, cydia issues, repo issues, legal issues & donations! Not to mention the constant scrutiny from people who have enough money to just go out and buy new unlocked phones)

    well .. fortunately for the developers of all of those “cracked” apps and so fourth, will be happy to know. I do not use a single app on my phone (jailbroken) unless its free or CYDIA tweak only ..

    It does not “advertise stupidity” It simply states that you are going to have to learn something about the computer your using!

    Sorry for the rant, good luck with all of your iOS 5.0.1 installs :)
