Hey, just wondering if anyone else is having this problem?? I got my iPhone 5 (black/16) sept. 21st and just over the last few days I have this intermittent problem, when I press the sleep button, it sometimes does not work. Also, sometimes I push and hold it to turn it off and it acts like I just pressed and let go. NO I have not dropped the phone or abused it in any way, NO nothing is different. It acted this way w/iOS 6.0.1 & 6.0.2. ...This is the first iPhone in almost 4 years that I've had a problem with this (or any) button...never before. Anyone else have this problem? Should I take it to Apple, have it replaced?
