We have some information for those of you seeking a jailbreak for the recently released iOS 4.2.1 GM that Apple put out. An updated version of Redsn0w will jailbreak your iOS devices, but those of you who wish to unlock should pay attention.
If you are not interested in unlocking your iPhone 4 and just want to find a jailbreak for iOS 4.2.1, you’ll find a useful article over at RedmondPie, which provides detailed instructions as well as download links in order to get everything working.
However, unlocking iPhone handsets remain as popular as ever, so we should point out that you should ‘avoid’ downloading Redsn0w 0.9.6b3 if you want to unlock your device. Instead you should wait for further instructions from the iPhone Dev Team, as they are currently in the midst of working on a new untethered jailbreak which will allow you to unlock iOS 4.2.1 with ultrasn0w.
It sounds a bit confusing, but really it’s not. If you need a jailbreak for iOS 4.2.1, hit the link to RedmondPie above, for an unlock, stay tuned for further news from us. If you do decide to jailbreak, let us know how you get on and if it worked for you or not.
