Here is a good news for iPhone 3G and iPod Touch 2G jailbreakers, as the Dev-Team has just released a fresh beta version of redsn0w, version 0.9.6 beta 1, which allows users to jailbreak iPhone 3G and iPod touch 2G on iOS 4.1/4.2, the new redsn0w version uses the same pwnage2 DFU-mode exploit that was previously used since the 2.x days.




The Dev-Team warned who use ultrasn0w to unlock their devices, to stay awy from Redsn0w, and wait for PwnageTool to support 4.1, that is because to use redsn0w at 4.1, you need to already have updated to official 4.1 from Apple,if you do that you lose the ultrasn0w unlock, possible forever. The release redsn0w is only available for Mac, as the Windows version needs further testing.


 

This Redsn0w beta release supports:
  • iPhone 3G and iPod touch 2G only (for now)
  • Mac OS X x86 only (for now)
  • 4.1 or 4.2 firmware from Apple
