Bummer... got an iPhone 4s, white 16gb via Sprint last week, my first iPhone ever! 
Noticed Saturday after playing with it for a couple hours (it got fairly warm) the entire right side of the screen became unresponsive. For instance, the O and the backspace on the keyboard no longer worked.
Everything else worked fine, but the touch screen went bonkers.
So, I performed a full restore, started it back up and it worked fine, I thought no probs.
Was using it again last night, playing a game, got warm again and then the touchscreen went nuts, opening and closing apps, the right side was dead, blah blah.
So I let it sit, when it cooled down, it worked fine again, but as soon as it gets warm the screen goes nuts.
Anyways, I guess I'm screwed since everyone is out of stock.
Love my phone, but dammit Apple, I expected better from your factories.
