I got my iphone 5 in late october. About an hour after unboxing it, I was treated to the erratic touchscreen. So I called ATT and they sent me out a new one. About a week or so ago, I got a camera spot (chip on the lens). So I went to the apple store, and they swapped me a new one (refurbished) no questions asked. Yesterday, I was using it and the touchscreen was occasionally freezing up. Today, it's more like the touchscreen occasionally responds. so I am going to have to take this one back now. This just seems utterly ridiculous to me. Anyone else have an experience like this?
