i originally bought this iphone in late july 2010. anyways for the last 4-5 months i've been noticing that the phone won't register clicking the home button sometimes. this happens at random times throughout the day and i can't predict when it happens. I took it into the apple store and the genius said he couldn't do anything about it because i couldn't reproduce the problem. This is really annoying because i have to click the home button up to 20 times before it starts functioning normally again. I don't know what to do and my warranty expires in 1 month.
