I'm pretty sure the touch screen is bummed on my iphone. The bottom 4 icons do not respond at all no matter how i press them. But the funny thing is that the slider icon to unlock and answer calls works flawlessly, in the exact same area that pressing does not work. I'm getting ready to sell it as broken and get a new 3g but I'm just wondering why the slider still works? Is there a different sensor for swipes than presses? It just doesn't make sense. I've restored twice from DFU and now I'm just upset. No warranty because it's unlocked. Sad times I think. Any suggestions?
