So, this happened twice yesterday.. I'll be using the phone normally (a few texts, phone calls, whatever) and put it back in my pocket. A few seconds later when I go to pull it out again, the phone will be completely off. The center button won't wake it up, the top button won't either. I tried plugging it in to the charger, nothing. Held the center button, nothing. The only thing that worked was holding the center and top buttons down for a long time (around 10 seconds?) and even that took 2-3 attempts. What the heck is going on? I have applecare so its not a big deal, but the phone is only 2 weeks old.
