Hi everyone. I am in serious need here. I have the old iPhone not 3G. I had it unlocked to bring it to Canada. It was working great with my old sim card from my other phone. I recently updated (downloaded) the new software, and now the phone wont work at all. I called customer support and asked for help, they only told me that I need to restore it to the old software. If anyone knows how to do this, PLEASE help me out. I would owe them SOOOO MUCH... I will name my first born after you.
