I'm an idiot! I continued my search and just realized that I accidentally turned the mute button on when I slipped my iPad into my thin SFBag sleeve! Ugh. I'm embarrassed! I hope this post might help someone else as dense as me! Original post below: It's really weird: my iPad 2 is working fine but just late last night, I noticed that there's no sound when I receive/send mail, wake it from it's sleep, type, etc. When I play a movie, I can hear the sound perfectly well. I hope I'm just doing something really stupid and won't have to get a replacement. PS: yes, I went into settings and I think I've got everything turned ON. Also, I powered down completely but I've still got this problem. I hope someoneout there will printout a simple solution. Thanks!
