I have just been tipped off by one of our readers who has got a reply from Chpwn, confirming that Cydia is now ready for primetime use on iOS 4.2.
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.
Geohot’s Limera1n used a userland exploit from Comex to make an untethered jailbreak for all iOS 4.1 devices. While Apple cant patch the original bootrom based Limera1n exploit, the userland exploit though can be patched easily by a firmware upgrade such as iOS 4.2.
Apple has seeded the final GM release of iOS 4.2 to developers. The recently released Redsn0w 0.9.6b2 (based on Geohot’s Limera1n) can jailbreak all of the current iOS devices on iOS 4.2. This has also been confirmed by MuscleNerd of the iPhone Dev Team.
PwnageTool with Limera1n will Jailbreak (Untethered) iPhone 4, iPad, iPod touch 4G on iOS 4.1, 4.2 & Beyond for Life !
Just a couple of hours back, iPhone hacker MuscleNerd tweeted to say that he thinks that iPhone Dev Team has found a way to extend current untethered jailbreaking tools to work on all A4-processor based iOS devices.
The SHAtter exploit based GreenPois0n tool is all set to arrive on October 10. But unfortunately, it will only jailbreak the fourth-generation devices like the iPhone 4, iPad, iPod touch 4G and the Apple TV 2G. This limitation is because of the nature of how the low level bootrom exploit SHAtter works.
PwnageTool Bundle for jailbreaking iPhone 3GS (old bootrom) on iOS 4.2 Beta 2 has been released by msft.guy. You can use this bundle with existing version of PwnageTool to create custom firmware files which are jailbroken and hacktivated for iPhone 3GS. But as always, this bundle is meant for iPhone 3GS with old bootrom only. Those of you who are with new bootrom will have to wait for SHAtter exploit based PwnageTool or GreenPois0n jailbreak tool, both of which are expected to release soon.
Even though the newly released Redsn0w 0.9.6b1 officially supports iOS 4.1 and iOS 4.0 only, but MuscleNerd of iPhone Dev-Team has confirmed that iOS 4.2 Beta can also be jailbroken (on iPhone 3G and iPod touch 2G only) using this release of Redsn0w but don’t expect everything to work flawlessly.
