So i was walking down the street, saw a friend of mines, added her number in my phone, then put my phone in my bag. 5 min later, my iphone wouldn't turn on. It had a full battery and working just fine before. I have it connect to my macbook and its trying to sync the iphone in itunes. Its also trying to grab the photos from the iphone with iphoto. Any suggestions on what to do? I also took my sim card out and put it back in.
