So i've had my iPhone since they did the price drop and its got a good plastic case with the protective film...i baby is the point. But lately I've had problems where, like the other day for instance, i just got done with a call, i hit 'end call' and my screen goes black. I hit the home button and nothing..i hit the power bottom and nothing. i double tap the home button and nothing. i then hold down the power button to try to reset it ...nothing. I let it sit for about 2 minutes and starting pushing buttons again cuz now i'm going to flip out. after about 5 minutes it comes back on. i've had this similar thing happen about 2 times in the last month. I'm fully updated and my phone is in perfect condition...anyone else getting this? any ideas before i just take it to apple.
