I unlocked my 3GS (3.1.2, 05.11.07, model MB717LL) using blacksn0w and since I did that most (not all) the time when I power cycle the phone it comes up in SAFE MODE with an option to reboot. When I reboot it comes back fine. Everything works fine but the "crash" concerns me. Is this "normal" for an unlocked phone? If I uninstall blacksn0w will it also remove the unlock?
