Have any of you guys had the freezing up issue? I'm running 7.0.4 on an iPhone 5 and iOS 7 will constantly freeze up. I just plugged up to iTunes, restored the iPhone, and setup as new (*not* from backup). I kept opening the default apple apps and it still freezes. Once it freezes the touch becomes unresponsive. I have to lock the phone, then swipe to unlock, then you can use it again. I actually just got a different iPhone, restored from backup, and this iPhone doesn't freeze up any - which again, is from the backup that my previous iPhone was using. Does this sound like a hardware issue or something that could be resolved in 7.1? It is unfortunately out of warranty, and I'm sure Apple would charge an arm and a leg to replace. Just curious as to if anyone else is having these freezing issues?
