My iPhone's ringer switch, when on vibrate, occasionally thinks it isn't and then it is and it goes back and forth thinking it's on ring or vibrate even though the switch's physical location is on Vibrate. It just sits there vibrating for a while and you can see the bell and the bell with the slash on the screen until it stops. It's extremely annoying when it's in your pocket and it gets brushed the wrong way and it does this. My phone has a few obvious bangups... nothing major though, but there's a few scratches, a big series of dings on the back on the upper left corner by the camera where it was dropped on concrete, and two dents in the back where I walked into a table with it in my pocket. Because of these little problems and because it's so intermittent that the ringer switch glitches (it's near impossible to force it to glitch) I'm thinking it'll be hard to get it replaced by Apple or they'll want to send it off. Does anyone know how successful attempts are to get a phone replaced in store "no questions asked" or based on unverifiable testimony? I can't just keep trying to bring it in because the nearest store is 60 miles away.
