iPhone iOS 4.2 Jailbreak & Unlock Notes
Update 12/1/2010: iOS 4.2 download has been released and you can now unlock and jailbreak the iPhone on iOS 4.2 by downloading redsn0w 0.9.6b5. This is either a tethered or untethered jailbreak depending on your iPhone.
With the release of iOS 4.2 imminent, the iPhone Dev Team has posted an update regarding the status of jailbreaking and unlocking the new version of iOS.
The message is this: if you want to unlock or jailbreak your iPhone you should avoid the iOS 4.2 update until the Dev Team has sorted through the release.
Here’s the takeaway from the Dev Team blog post:
- All devices on all iOS firmware can be jailbroken
- Jailbreakers should wait to update to iOS 4.2 until there are new releases of Cydia, PwnageTool, etc
- Unlocked iPhone owners should not update initially, stay where you are to preserve unlock
- NOT all iOS firmware on all devices are capable of being unlocked
- There are currently no unlocks for iPhone 4 with iOS 4.2, but it’s being worked on
- iPhone 3G and iPhone 3GS will have an unlock available first, but avoid the iOS 4.2 update initially until the Dev Team clears the release.
We do know that redsn0w is capable of jailbreaking iOS 4.2 if the 4.1 IPSW file is used, but unless you are committed to being on the bleeding edge, it’s best to wait for further instructions from the jailbreak community.
In the meantime, iPhone unlockers can save their SHSH blobs to be safe.

If you have never done those latter steps before, then our friends at lifehacker have a nice walkthrough detailing this process in full. If you follow the guide to finish, your Mac will automatically look for and mount a Windows or Linux shared drive and then back up to it using Time Machine. 


Every once in a while you’ll come across a song or video on the web that you just can’t find anywhere else. Maybe it’s a remix, maybe it’s an interview you want to listen to, whatever it is, you can easily convert that web video’s audio track to an MP3 file, which can then go onto your iPod or iPhone. Here’s how to convert any video to an mp3 file for free.

Bluetooth is great since it allows for anyone to wirelessly sync hardware together. It’s typically turned off by default in iOS, so you’ll want to turn it on first if you intend to use the Bluetooth connectivity options.
