Help Will my Infuse work on T-mo if swap sim cards with my Blackberry?

[Wifi-Naught Odin]

Why would I do this? Because I don't have a contract, sim card, or service (other than wifi & gps) on my Infuse (*by AT&T, device only) and my Blackberry plan's free (company plan).

Already asked my boss. He doesn't care what phone I use as long as I can get their calls. I'm not concerned about data quality or speeds (the Blackberry's t-mobile plan's only voice and edge). But it would be nice to receive company calls on the Infuse and not have to carry both gizmos around everywhere.

Thanks in advance!

You can do this IF you unlock your phone. The first time you power up with the T-Mobile SIM, it will prompt you for the unlock code. It's a 1-time deal... once you successfully unlock, it's permanently unlocked for all carriers.
