I have the iPhone 3G 16GB Tried different chargers and through the computer and wall. Tried taking it to the Apple store and it's not covered by the warranty apparently I think there was a little dirt / moisture at the bottom where it's supposed to be plugged in for charging .. Which leads me - is my only option is to sell it? But then, if I attempt to buy another one through AT&T, will they charge me that full price and not the upgrade price (since I already used it on this iPhone for that special price) ? I was wondering if I could just get the iPhone 3G 8GB for $200.00 but wasn't exactly sure if that would be the price still .. I would get another phone but I love iPhones web browser and email stuff..
