This is my first post in the forum. I joined just for this! I have had an iPhone 2G for a little under a year now, meaning I should still be covered with my warranty. It's unlocked and jailbroken, and I'm currently using Tmobile as a cellular service. I'm having pretty serious wifi issues and have tried every fix I could come accross on the internet with no luck. I figure now my only choice is to replace it with a new one. I don't have an AT&T phone number, and don't think I ever registered the iPhone when I purchased it since I didn't set it up via AT&T. How can I go about returning my phone for a new/refurbished one? I am completely helpless without my wifi. PLEASE HELP!!
