Hey everyone, I have a new iPhone 5. Restored from my iCloud 3GS backup. My 3GS used to sporadically reboot. I would be using my phone and all of a sudden the screen would go black and the apple logo would appear and then the phone would start back up. This just happened on my iPhone 5 after receiving a text and going to read it. I swiped to read and the apple logo appeared for 4 seconds and I was back at the lock screen with battery time usage stats reset indicating the phone was reset. Any idea why this would happen? Thanks.
