Hey guys, Today I noticed that my 4S mute switch is sticking a bit. It still moves and switches between ring and silent, but it is kind of slow to move, and just sort of floats over (with some resistance) instead of clicking into place. I've found that if I blow into it, it begins to click again. I take good care of my devices, though I do not use a case on the phone. Has anyone else experienced this? Do you think it would be covered under applecare to have it fixed? I assume there's a chance they would consider this accidental damage, though I have no idea what I could have done. Just curious.
