As expected, iPhone Dev team has just released a new version of Redsn0w (Redsn0w 0.9.7b1) that implements the “backup plan” for iOS 4.2.1 untethered jailbreak.
Redsn0w 0.9.7b1 can be used to (untethered) jailbreak iPhone 4, iPad and iPod touch 4G on iOS 4.2.1. Please note that Redsn0w 0.9.7b1 is meant only for beta testers and not for the general public as there are still some known issues that need to be addressed.
We had reported yesterday that the untethered jailbreak for iOS 4.2.1 by Comex may not be released before Christmas.
But iPhone Dev team is on track and has announced that it is planning to release a new version of Redsn0w that implements the “backup plan” for iOS 4.2.1 untethered jailbreak over the Christmas weekend.
A forum member of ModMyI claims that he was not able to jailbreak his iPad that he had bought recently using Redsn0w.
This has led to speculation that Apple might have patched the limera1n exploit that has been used in Redsn0w to jailbreak iOS 4.2.1 in newer iPhones, iPads and iPod Touches that are being shipped.
MuscleNerd of the iPhone Dev Team has revealed that he has managed to get untethered jailbreak to work on iOS 4.2.1.
This is good news for users who own an iPhone 4/iPad/iPod Touch 4G/iPhone 3GS (with new bootrom) as currently Redsn0w and PwnageTool for iOS 4.2.1 can jailbreak newer iDevices on iOS 4.2.1 but it is tethered. iPhone 3G and iPhone 3GS (older bootrom) users are the lucky ones to enjoy an untethered jailbreak.
iPhone Dev Team had released PwnageTool and Redsn0w that allowed users to update their iPhone 3G or iPhone 3GS’s baseband to 06.15.00 along with Ultrasn0w 1.2 to unlock it few days back.
Some users have reported significant loss of GPS signal after upgrading to baseband 06.15.00. iPhone Dev team has also confirmed that though baseband 06.15.00 is capable of GPS, it might require further hacks.
