My friend has an unlocked ATT 8300 for sale. And someone who has T-Mobile is interested in purchasing it. My question is, what services will the kid have when he puts his T-Mobile sim card in the unlocked curve right away. I don't know if the kid will be getting BIS put on his account or not. I'm guessing that he will be able to make calls, I'm just not sure about everything else, e.i. text, mms, e-mails, internet and such. Any help or thoughts would be greatly appreciated.
