I went to dial a number a few minutes ago and instead of making the audible tone tone noises it vibrated. I checked and I have audible touch tones selected, all my volumes are up but I can't figure out why it's doing this. I powered down and pulled the battery, restarted and still... I know it's petty, but it is going to drive me nuts not having audible touch tones when making a phone call. It also does not make any sounds when I activate the dialpad during a phone call, which it did before. UGH. Any ideas?
