I'm really liking the 5s. I bought it on launch day and I continue to be surprised with how great of an upgrade it is from my 4S. But I have noticed that it crashes sometimes. Like 5 times since Friday. Usually while using the camera, but it just happened in Safari. The phone locks up for a little while and becomes completely unresponsive. Eventually (after a minute or two), it will respring. I assume this is just optimization that isn't quite there with iOS 7 and the new processor and that Apple will fix it up soon, I hope. I can try restoring, but I'd really rather not as I just did all of the setup procedure two days ago. Anybody else seeing this?
