This is a better question for the T-mobile forum. What I remember reading there was that you have to specify a MyFaves compatible phone on your account. You can do that easily online, I am supposedly using a Blackberry in order to be able to order the Blackberry internet plan. So you'd have to change your phone online and order the MyFaves plan and then use it. I believe that it is just an account feature and not really dependent on hardware. Just confirm this over in the T-Mobile forum though.
