So my iPhone 4 (32G) arrived today from an angel (the fedex guy). I slowly opened it and backed up and set up the new piece of tech heaven. After about three hours I was on a phone call and then got a text and then put the phone back in my pocket. About 10 minutes later I get out of my car and pulled my phone out of my pocket. It wouldn't turn on. I tried again and again. I plug it into the charger, nothing. I connect it to my macbook and load iTunes, nothing. Freaked out, I grab the land line we have (yes, we have one) and called Apple. The guy at Apple was just shocked that I experienced this problem within hours of setting up my new phone. He said it was the first called he'd heard of regarding this "unresponsive issue". He asked if I had done a hard reset by pushing the power and home buttons at the same time for 15 seconds. I had not so I tried it and like "magic", it loads up and acts completely fine. He documented my case and informed me that I may get a call from Apple due to this issue and he gave me a case number in the event that it happens again. (It better not for $330) Just thought I would share my daytime nightmare. I hope that this doesn't happen to anyone else. Enjoy your new iPhone 4 everyone!
