This is only my second post on these boards. First off I want to say how much inside tech info I've picked up on these boards from BB philes. There is much to know that I would have not known otherwise.
As far as a case is concerned. This is my third BB. I traded in an 8700 for the Curve. I like the Curve although battery life is suspect.
But here is what I am using for a case. The Curve fits perfectly. Since most of the time I have my BB on vibrate it works for me. And a profile change is a simple "F" key stroke.
Lowe Pro Camera Case.
I know this doesn't work for everyone, but it has been a great alternative.
