Hi everyone. I just got an iphone back in Sept. of last year (not really planning on it my old phone died). I thought 8GB would be plenty of space at the time, but I was sadly mistaken. My memory is currently almost full, so I was wondering how I could go about exchanging this one for a 16GB or maybe the one that will most likely come out in the summer. I have the 2-year contract with AT&T and I don't really know if they can transfer the bill over to the new one? Please don't tell me I would have to pay for 2 iphones just have a few extra GB!! Any help would be appreciated...
