Hello I have an AT&T 32GB Black iPhone 5 and it seems that ever since the update to 6.0.1 my sleep/wake button does not work reliably. After numerous presses the button seems to work but it is extremely frustrating and I am not sure if it has anything to do with the update or if it is a faulty button. I am in the process of updating it to 6.1 to see if this will help. Thanks for the help!
