This is a tutorial on how to perform an untethered jailbreak of your iPhone 4 on 5.0.1 using RedSn0w for Windows. The same steps for Mac version.

This procedure will cause you to upgrade your baseband. For those how rely on an Unlock must stay away from this and update using a custom ipsw.

Update #2: Redsn0w 0.9.10b4 released to address the iBooks issue for jailbroken devices.

Update #1: The b3 version of redsn0w fixes a problem where re-running redsn0w over an existing jailbreak would cause MobileSubstrate-based apps to stop running until MS was installed again. Now you can re-run the redsn0w jailbreak step without worrying about that (but still remember to de-select the “Install Cydia” option if it’s already installed).
