according to some of the threads around here and other forums, tmobile will be cutting off access to certain third party apps like opera mini if you're using a regular tmo internet plan. if thats the case and they plan to implement this and you're on tmo, then you should probably be lookin into a blackberry data plan.

tmo users dont have data usage charges.
