Interestingly enough I was talking to a friend of mine earlier who owns the HTC One X for AT&T. I was explaining to him a problem I started having with my phone going completely crazy earlier today and he started to laugh. He had the exact same problem and it was because he had never turned off Fast Boot since getting his phone. Leaving it on always prevents the phone from ever really going to sleep or resetting issues or cleaning out things on the phone taking up memory. Once he unchecked fastboot this issue never happened to him again. I have since unchecked fastboot as well, I shut the phone off for 5 minutes then powered up and then did a reset and so far no issues at all, and in fact the phone feels a bit faster. Just a heads up to anyone like myself that didn't know this. I always just felt that the fastboot option was great because it literally restarted the phone, well, fast. Even unchecked this phone boots up pretty fast.
