Well I just upgraded my blackberry to the 8330 and I love it. I've always loved blackberrys. & I was wondering what is some good stuff that I should install on it, or any apps you think are cool?
I always recommend reading the 101 series first. The link is in my signature. As far as apps, that's a personal choice. What I find to be useful, may not be suitable for someone else.
Don't be shy about asking questions, there's always an addict around that can assist you.
