Hey! This week I realized that after using my friend's iPhone my handset's sleep wake button was malfunctioning. When I press the phone's sleep wake button the button presses down and goes in a little and functions as should. It does however seem as though it's spring mechanism is failing because that obvious click is gone that every other handset I touched is functioning correctly. I have scheduled an appointment with the genius bar for later this week but I am worried that they will do nothing or say that this is normal procedure. I am under warranty so there is nothing to worry about on that front. I am asking to see what your opinions are on this issue. I hope that everything works out later this week!!
