Redsn0w 0.9.6b1 for Windows to Jailbreak iOS 4.1 [Guide]
The iPhone dev team have released RedSn0w 0.9.6 beta 1 for Windows to jailbreak iOS 4.1 on iPhone 3G and iPod Touch 2G. If your iPhone 3G relies on Ultrasn0w unlock, stay away from this Redsn0w release, as it updates your baseband to the latest version, making it impossible to unlock (for now).
Redsn0w 0.9.6 can also jailbreak iOS 4.2 on iPhone 3G and iPod touch 2G, but that comes with a high risk warning.
This is a beta release 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 have an “MC” model of the ipt2g, your jailbreak will be tethered…sorry! (Consider rolling back to a FW supported by jailbreakme.com or spiritjb.com)
