The following is an updated tutorial to assist you in achieving an untethered iOS 5.0.1 jailbreak for your iPhone, iPad, and iPod touch using redsn0w 0.9.10b3. The untethered jailbreak is currently for non-A5 devices only (will not work with iPhone 4S or iPad 2).
Warning: do not proceed if you’re unsure about what you’re doing. Follow the guide at your own risk.
Should I use PwnageTool or redsn0w to jailbreak?
PwnageTool enables you to create a custom IPSW to update to iOS 5.0.1 in iTunes, so you can preserve your baseband. This is important if you use ultrasn0w to unlock your phone.
The latest version of redsn0w now includes options for creating a custom IPSW in the ‘Extras’ menu. If redsn0w doesn’t work, try PwnageTool to jailbreak instead.
