Jailbreak iPhone, iPod Touch, iPad

MuscleNerd tweeted today that the recent redsn0w utility is able to jailbreak the iOS 4.1 beta2 on iPhone 3G and iPod Touch 2G. This is useful for developers only, however good news for everyone.

Here’s some info from the DevTeam wiki page:

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.

Hacker msftguy created unofficial PwnageTool which allows to upgrade to the pre-release of iOS 4.0 GM while keeping your jailbreak and old baseband.

This is not an official release by Devteam, so we recommend to wait for the final versions of both iOS 4.0 and PwnageTool.

For the advanced users who want to experiment here is a link.

Msftguy also provided a video:

Apple recentrly released new version of iPhone OS 4. it is called iOS 4.0 GM. Here is an update from DevTeam about iOS 4 jailbreak:

For those who can legitimately activate to the iPhone3G 4.0GM seed, the “point to previous IPSW” redsn0w trick works and will jailbreak your 4.0GM. The “trick” is to point redsn0w at the 4.0beta4 IPSW instead of 4.0GM (do this after you’ve updated to 4.0GM and activated through the new iTunes 9.2 on your Mac). Since the carrier unlocks aren’t yet supported at 4.0, don’t do this if you use yellowsn0w/ultrasn0w/blacksn0w. Many JB apps are still pretty buggy in 4.0, so again this is mostly useful only for developers of those JB apps.

Note: If you’re experiencing MobileSafari crashes, double check that you’re running the version at the bottom of this page.

For those without legit iPhone3G 4.0GM seed access, please wait until the full public 4.0 release for updates to the jailbreak tools.
