A tutorial to make tethered jailbreak iPhone 4 iOS 5.0.1 is shown below. Recently iH8Sn0w, the developer of the free jailbreaktool that allows us to create a custom iOS firmware, has updated the Sn0wbreeze version, reaching 2.8b11 version that supports iOS 5.0 and iOS 5.0.1 final. With the help of this free jailbreak tool we can maintain the baseband intact when switching to a higher iOS version.
Since it is a tethered jailbreak, you must run every time iBooty and reboot your iPhone 4 to access the jailbreak again. If you have baseband 06.15.00 you will be able to restore to iOS 5.0.1 and iBooty will help to exit from Recovery Mode.
