Just hours after the release of iOS 4.2 GM by Apple, @MuscleNerd of the iPhone Dev-Team has confirmed that redsn0w 0.9.6b2 can jailbreak this Gold Master seed of iOS 4.2, however it should be attempted with caution only by advanced jailbreakers and developers.
This is what @MuscleNerd said:
“LOL yesterday’s redsn0w does JB today’s 4.2GM seed but see Update #1 http://is.gd/gAP3p about why most JBers shouldn’t yet”
Here is what it says on the official Dev-Team Blog:
“Update #1: Today Apple released to developers the GM seed for 4.2. Tinkerers will find that yesterday’s redsn0w jailbreaks today’s 4.2 GM seed, simply by pointing redsn0w at the 4.1 IPSW (rather than the 4.2 one). Right now it mostly only makes sense for JB app developers to do that because many apps (including Cydia itself) need to be updated for 4.2. However, if all you want to do is enable afc2 (to use iFunBox or other file browsers), or to tweak settings like Battery % and Homescreen wallpapers, then go for it (if you have valid paid access to the GM seed). Be sure to uncheck the Cydia box, though! Ultrasn0w unlockers should stay very far away from this!!”
The latest version of redSn0w 0.9.6b2 is based on Geohot’slimera1n exploit and allows restoring your iOS device to custom firmwares on Windows just like Pwnage Tool does for Mac while preserving the old baseband and allow unlocking with existing version of ultrasn0w on iOS4.1. If you are on iOS 4.1, you can safely use the latest version of redsn0w found here to jailbreak your iOS device. Feel free to leave your comments below!
