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 fireware reinstall and just do a reset on the phone and proceed to to jailbreak and unlock?
