I saw where you said they are "subject to carrier compatibility". So that means they will only work on certain carriers?

I think now I will have to wait before purchasing a new Blackberry. Somehow I have a feeling that T-Mobile will block them since T-Mobile uses the OZ IM program and that uses SMS. They would lose a lot of revenue by offering this.

Are these programs going to be available for download on any blackberry or will they be bundled on new handhelds only?
