Picked up a new 920, the bluetooth on the 8830 worked for one day, then I had lock up on the TT and no bluetooth link up. I had the TT replaced and 8830 will find the new 920, the TT recognizes the 8830, but they will not link. I spent an hour and a half on the phone with TT tech, and after trying every trick in their book, I was told that the TT is a hit and miss with the blackberry and TT tech did not have a solution. Yet in this forum some have successfully connnected their 8830's with 920's. What gives?
