Hi guys! Please help me, i wanna know: Im using an Iphone 2G 3.1.2.. I have upgraded it, and jailbreak with Blackra1n, and unlocked with Bootneuter. Can i downgrade it back to 3.0 and use the Pwnage tool to jailbreak unlock? Will there be complications? I have found that 3.1.2 is buggy, sometimes calls does not come trough etc, and i have to reset my device. Please comment, so that i know its safe to do so! Fanks from S Africa!
