I know this sounds dumb, but since I updated to that new iPhone software Thursday my phone has not made any noise while ringing. I have verified over and over inside of "sounds" that my killer Slayer ringtone is selected, and I can hear it play back in preview. I have also confirmed over and over that the volume selector on the side of the phone is at max. No dice. Incoming calls make no noise, my phone is not making any noise at all in fact, except for previewing my ringtone... text messages, keyboard clacks, nothing. Anyone got an idea for me? Thanks.
