Earlier today we reported the news of the release of the iOS 4.1 beta 2 by Apple. Musclenerd of iPhone Dev Team has mentioned in his tweet that the iPhone 3GJailbreak iOS 4.1 Beta 2 on iPhone 3G and iPod Touch 2G (Non MC model) could be jailbroken on iOS 4.1 beta 2 using Redsn0w 0.9.5 beta 5. Here is his tweet.

Jailbreak iOS 4.1 Beta 2 on iPhone 3G

The Dev Team also mentioned the following.

If you’ve updated to 4.1beta2 on iPhone3G or iPod2G(non-MC), you can use this redsn0w from June to jailbreak. Just point it at the 4.0 IPSW (the public one, not the developer GM one).

(Yes – point it at the 4.0 IPSW even though you’re at 4.1beta2).

Don’t do this if you need the ultrasn0w carrier unlock!!

Note 1: This won’t hacktivate your iPhone3G – but for those with legit access to the 4.1beta2 this shouldn’t matter. Please don’t pirate Apple software

Note 2: If you’re at 4.1beta2 you’ll probably experience network problems after jailbreaking. Until a new version of redsn0w is released, you may need to rely on afc2 access (such as FunBox-like file browser programs) to manipulate your filesystem.

Note 3: This is recommended only for power users who can deal with the problems that will pop up as the JB apps fall further behind the beta firmwares.

If you want to jailbreak iPhone 3G on iOS 4.1 beta 2, then follow the guide posted here.

NOTE : If you find Cydia as a blank icon after the iOS 4.1 beta 2 jailbreak on your iPhone 3G, then take sources and add the repo ” http://apt.saurik.com/cydia-3.7 “.
