I had no sound when receiving a imessage, text or email.
Here's how I got it fixed. I went into itunes. The volume was all the way down. I turened it up and all is right with the world again. If you think about it all these sounds are sync'ed in iTunes so...I think it's a bit of a needed fix by Apple, but you know-Apple will do ''what'' Apple wants- ''when'' Apple wants. Until then---------
