    Default updating with tinyumbrella
    Alright so am getting ready to update my iPhone3GS 4.0.1 (8A306) Model: MC133LL Baseband: 05.13.04 - 6.4_M3S2, so first things first i can still unlock if i preserve this baseband correct? If so using tinyumbrella i restore to 4.1 and this should protect my baseband corrent. I am reading this as a guide to update. Then i will jailbreak with GP. Am just trying to make sure i can still unlock while updating. Thanks for all your help.

    If you restore to 4.1 it will update your baseband on a 3GS. Don't do it if you require an unlock.

    Check if you have new or old bootrom and if it's old, look at Snowbreeze.
