I am looking for a mount with a long arm enough to keep the BB closer to me so I don't have to reach up for it. I am using my BB with Pandora & Slacker Radio (just won 3 month subscription) and I would like to take advantage of it. I hate to just pick it up and look at which song is next, or who is singing it.. etc..
I have been using a universal mount that I bought back when I had a Palm Treo 700WX. The one arm moves in for adjustment and the two bottom mounts also move for adjustment.
In fact I just used it this past week on a 5 hour trip and it held the 9700 fine for the whole time. Also made it easy to speak with the wife for an hour through the speaker function on the phone.
I was also just looking at BB's site and they also have a window mount for the phone but it looks like it is a short arm.
