IPhone Sleep Button Might Be Broken

Question

I recently noticed my iPhone 3G sleep button might have an issue. It works fine, so I am not too concerned but the button is uneven. The left side of the button is very low. Flush even with the iPhone itself. This isn't something most people would notice but how is your sleep button, even or uneven? is the left or right side lower than the other?
Should I be concerned with this button? Should I take it to a Genius?

Answer 1

I actually have an issue with the sleep button and the software... It seems like the sensor that takes the command from pushing the button for the phone to enter standby, is glitching. I have restored my phone 10 times in the last three days, thinking it was a software glitch.
What happens is, the phone can be sitting still, on a desk, flashing the background back & forth, like I am pushing the button. If I somehow get to the home screen, it will make the "click" noise and put itself into standby. Sometimes, it will miraculously turn itself off, then back on.
I treat my phone like a baby, it's never been dropped, scratched, shaken, and is protected in a case, just to be safe.
I am putting one last effort into it, by doing a long format (doing the reset that takes an hour or so to totally wipe it back to factory-like settings), and seeing if that somehow fixes it. I can't narrow it down if it's hardware based, or software based, as the button doesn't sit lower than it used to, and doesn't "feel" any different. I have a box coming from Apple, just in case.
I've been without it for two days, and will most likely get a crappy refurb (oh wait, "service" model, as Apple calls them) like with my 1st gen. We'll see!
