Hi! i have a BB8700 from Tmobile that runs a V188.8.131.52 software and V4.3 desktop manager. I recently have been experiencing a problem with the cell constantly turning off whenever I use my Jawbone for no longer than 10 mins. After a cold reboot it resumes only to go out again. What is funny! When the phone is being charged I have NO problems using the BT. I've have contacted Tmobile several times which has came to NO avail, and frankly speaking I'm at my at last resort-throwing the phone against the facking wall. I've erased and reinstalled the apps so many times i can't remember, yet the problem still persist. Any help plz! Show me some BB love. Thx!
