Ok, this is a weird one. It's happened to me twice now. This time I can't get it to recover. Here's what happened.
1. listening to music in the car using a tape converter plugged into the 3.5m jack.
2. Call comes in and I answer without unplugging the 3.5m jack.
3. I can hear the caller through the car speakers but, without a mic, they can't hear me.
4. Unplug 3.5m jack without hanging up or hitting any other keys.
Phone audio is now locked to the 3.5m jack and I can't get it to recover

Tried the following:
o took out the battery for a few minutes
o *228 option 1
Called VZW. Tech suggests we reset the phone to factor defaults. That means I'll lose all my custom settings. I'm willing to try this but would like to avoid the PITA if I can.
Any other, less intrusive, suggestions?
