Hi, I have some question about unlock and hacktivate: 1. If I update firware to 4.1 through iTunes, it will also update my baseband, no matter what device I have. Is this right? 2. If I update to 4.1 with custom firmware created by Sn0wBreeze, it wont update my baseband, and I can unlock by UltraSn0w. Is this right? 3. If I use "hacktivate my iphone" feature in Sn0wBreeze, I dont have to put in official iPhone carrier SIM, it will be activated after restore (with custom firmware) and I can go to Cydia to download UltraSn0w. Is this right? Please Register or Log in to view images New question: 4. If I update my firmware through iTunes, my baseband were updated. So if I have SHSH for 4.0 or smt lower, and I do downgrade, will my baseband also downgrade?
