Do you have a Data Plan on TMo? Then yes, BBMessenger will work on the BlackBerry.

Have you looked at our FAQ site applications?
3rd Party Application List - BlackBerryFAQ.com

i would also advise you attempt to make your questions clearer.

With a Data Plan, yes. Ant will work. But you must have a data plan on your service.
