Apple Devices supported are:
iPhone 3G
iPod touch 2G
Mac OS X x86 and…
Windows
4.1 or 4.0 firmware from Apple
From the iPhone Dev Team:
We’ve released a beta version of redsn0w for the iPhone3G and iPod Touch 2G at FW 4.1 or 4.0. It uses the same pwnage2 DFU-mode exploit that we’ve been using since the 2.x days. It does not include the SHAtter exploit developed by pod2g. Nothing new is revealed to Apple with this jailbreak.
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).
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)
How to Jailbreak your iPhone 3G or iPod Touch 2G using Redsn0w 0.9.6:
1. Make sure your supported iPhone or iPod Touch is already running iOS 4.0 or 4.1.
2. Start up Redsn0w 0.9.6b1
3. Select stock 4.1 or 4.0 ipsw
4. “Install Cydia” and any of the other options shown above, then click “Next”. Use DFU mode to install the jailbreak.
