Hi there guys! I have an iPhone 3gs 5.1.1 baseband 6.15. I jailbroke with snowbreeze with custom ipsw. I have a little problem with ultrasn0w (latest version) for unlocking to any network. My iPhone decides to reboot once the carrier reception reaches over 1 bar for some odd reason. This happens on every network i try. But when it is connected to power, it works fine. also the iPhone works fine when the recption is 1 bar, or with no sim, or searching for service? I live in New Zealand and before i had 5.1.1 i had 5.0.1 and ultrasn0w worked excellent. Any help? please? Thanks guys
