BlackBerry 8830

I currently have a Blackberry 8700 with T-Mobile and a Samsung U540 with Verizon Wireless. I am considering merging both into the Blackberry 8830 and discontinuing my T-Mobile Service.

I believe that my company will be able to maintain all that is on my current blackberry, but is there a way to merge my contacts from my regular cell phone on to the 8830?

Thanks.
