Any way to record a phone conversation on a blackberry?

Not with the native apps. Seems like I saw something about a 3rd party app for this, but I'm not sure. You could try a search on Handango or Google.

I know many exist on Windows Mobile I have not seen an application for the BlackBerry. Your other option is a dial in service that records your calls for you.

Or a physical device you can get at radioshack

Cool, I was just curious. Thanks.
