I got question, my friend want me to unlock his iphone 4 and it is Firmware 4.3.4 and baseband 4.10.01. I understand that I must use Gevey sim for it since the baseand is 4.10.01. As I was search for iclaried tutorial, I can't seems to find one for 4.3.4, only 4.3.3 and 4.3.5. Any idea why? Also, if I don't want to upgrade to ios5, can I skip the firmware reinstall and just do a reset on the phone and proceed to to jailbreak and unlock?

Another thing, my friend say the phone is never update and he got it when it launch but the firmware and baseband are updated at leasd once...
