Here is it. iPhone 3G and iPod Touch 2G users can now jailbreak their device running iOS 4.1 or iOS 4.0.
The Dev Team already released the beta version of RedSn0w, which uses the same pwnage2 DFU-mode exploit discovered since iOS 2.0.
IF YOU USE THE ULTRASN0W UNLOCK, PLEASE WAIT FOR PWNAGETOOL TO SUPPORT 4.1. DO NOT USE REDSN0W. That’s 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 (possibly forever).
– the Dev Team reminded.
Note: if you have an “MC” model of the ipt2g, your 4.1 jailbreak will be tethered…sorry! (Consider rolling back to a FW supported by jailbreakme.com or spiritjb.com)
– the Dev Team added.
This Redsn0w jailbreak version will only work for Mac OS X; however, Windows users will get the same tool as soon as the Dev Team ironed out the bugs. You can download Redsnow from the download links provided by the Dev Team here .
How to use it?
If you’ve already updated your device to 4.1 or 4.0, the next steps are:
1. Launch the beta redsn0w 0.9.6 Beta 1
2. Select your stock 4.1 or 4.0 ipsw (you’ve already used this to update your device to 4.1 or 4.0)
3. Select “Install Cydia” and any of the other options shown in the screenshot above, then click “Next”. Use DFU mode to install the jailbreak.
If you choose to “Enable battery percentage”, you actually toggle that off and on via Settings->General->Usage.
