It's at least the OS on my BB. PDAnet requires at least 4.6. Verizon only lists 4.5 for the 8830. I installed it anyway and got an error message.
If you have the minimum OS requirement, give it a try. A Google search for PDAnet and Blackberry takes you right to the page. Follow the instructions for BT, which don't require you to install the app on your computer.
