Dear Tree Frog
I have spent four days trying to reestablish a connection between my Q and my computer and was just on the verge of a major meltdown (no contacts, no appointments, none of my notes) when I found your post about this issue. I had to do a master reset in order to get my sound to come back. (Even though I had my regular volume and my headset volume completely turned up I couldn't hear anything.) It would fix itself for 10 seconds or so if I took the battery out and then it would crash again.
I remember way back a year ago when I spent 8 hours between Verizon help and Motorola help trying to get the Q to synch in the first place (it needed a firmware upgrade and a bunch of other patches to make it work) -- and I remember the Motorola guy had asked me to uncheck the "advance functionality" button. However my brand new phone had such ancient software that the option didn't even exist until the patches and upgrades were in place.
