  • As long as you preserve the baseband, you should be fine and don’t forget to save the SHSH blob with TinyUmbrella

    Will this process still work if I have unlocked Iphone4 with OS Version 4.0.1 and Firmfare 01.59.00. Need to upgrade to 5.0.1 with Unlock.

    Hi, will this process work on a T-Mobile sim card if I upgrade from iOS 4.3.5 to iOS 5.0.1 while preserving the baseband 04.10.01?
    I called AppleCare and was told that my phone is not locked to any carrier.
