iOS 4.2, at least from what information we have so far, is slated for release this Friday and it’s going to be a significant update for iPad (not so much for iPhone / iPod touch, though). And of course, there’s going to be a jailbreak to accompany the new iOS version. Here’s all you need to know.
As we posted in our guide on how to jailbreak iOS 4.2 GM on iPhone 3GS; Cydia and a lot of jailbreaking apps are completely broken. Both Cydia and JB apps will, of course, eventually start working and if MuscleNerd’s tweet is anything to go by, hackers chpwn and saurik are burning the midnight oil to get it working as soon as possible.
PwnageTool bundle for jailbreaking iPhone 3GS on iOS 4.2 GM has been released. You can use this bundle with PwnageTool 4.1.x to jailbreak your iPhone 3GS (old bootrom only), while preserving your old 05.13.04 baseband so that you can unlock it using Ultrasn0w.
