Hi everybody, i hope someone out there can help me with my problem, i just got a new BB 8900 (Unlocked/tmobile) from a relative in the US. i have not yet signed up with the local provider for blackberry service, but i was playin around with it via wifi, and it connected to my router and i can use the BB Browser to surf the web and all, but when i connect to gChat, it says data service unavailable?!

can anyone please help! really lookin forward to some helpful tips tht will eventually help solve my problem!

thank you
Basil
