    Hello all and first of all im sorry if im posting in the wrong place...

    I have my iphone 4 jailbroken on 4.1 with a baseband of 01.59.00 and its unlocked to be used with telcel (mexican company)...

    So basically what i want to do is go to ios5 and if i read right with my baseband im able to keep the unlock?

    I havent been in the jailbreak scene for a while so i want to know if im right or wrong on the steps i need to do...


    1.I have a mac and i believe i have to use RedSn0w 0.9.9b7 to first get a custom ISPW created that does not update baseband am i right?

    2. Use itunes and click option while clicking restore or update?

    I kind of tried to do that a while ago and itunes was giving me an error which i cant recall rightnow so i gave up...

    But i would appreciate any tips or steps i should take to go to ios5 and keep my unlock on my iphone 4....

    Thanks in advance

    2. You want option+restore. Never press update.

    It will be a tethered JB so if I was you I'd wait for an untethered version.

    Tethered is just fine, I just upgraded my iPhone on 4.0.1 with 1.59.00 BB to iOS 5 while preserving the baseband. Jailbroken it with Redsn0w and unlocked with Ultrasn0w. No problems at all :) (just don't turn off your phone without a PC at hand)

    I know but I don't think I would bother.
    How are most jb packages on it, still most not compatible with 5.0?
