For the past month or so whenever I try to unlock my phone by clicking the home button I have to push it about 3 times before it actually shows the unlock slider screen. Also once the iPhone is unlocked and I double tap home to get to my favorites it works about 1/4 of the time. Seems like my home button is slowly but surely going out. ANybody else have this problem? Also what should I do? Im apprehensive to schedule an apple appt because sometimes it works sometimes it doesnt.
