US mob phones - blackberry questions

question about US mobile phones
couple questions:
if i have a t-mobile (dont diss haha) plan for the blackberry, and i get a new blackberry in asia, will it still work + have the same additional blackberry services i signed up for (ie bbm and internet).

could i use a t-mobile bought blackberry (US) with an asian sim card, will all the blackberry services be provided as well, assuming that the asian number is also a blackberry plan? - I've heard you need to 'unlock' US phones to use it in asia, but not the other way around

Ask the same question on one of these.

You have to unlock your t-mobile blackberry to use asian sim card. I know someone bought a Motorola phone from Hong Kong and was able to use it here after unlocking.
