Did you have it working on an unlocked blackberry before? Maybe it requires a locked phone. I think Telenav caters to specific carriers. I could be wrong. I know I couldn't even do the Garmin trial because Bell wasn't on their list of carriers.
Maybe its because T-Mobile dsnt support OS 6 u may have to wait till they do. I have unlockd as well for T-Mobile and there a couple apps it won't support.
