Do you have a pay as you go plan for Blackberry...so voice and data service? I am in the States for a week, just trying to see if it would make sense for me to sign up for a pay as you go or stick with my Canadian carrier.
T-Mobile has a monthy plan for BlackBerry users that doesn't require an annual contract. I believe it's unlimited (you might also have to sign up for the voice part) and is BIS- not BES-compatible.
