$325/375....I was close. The 920 is a penta band phone....that has GSM 1800 which is the same as TMO 3G so if you get an unlocked one then you should be able to get 3G service without any issues. You won't be getting LTE though.
For getting 3G on T-mobile (pre-refarming), you need access to both 1700 and 2100. Yes, the Lumia 920 that were given to BUILD seem to have support for both of those frequencies. The one sold by AT&T though, most likely doesn't. One needs to be careful since there seem to be multiple variations of the phone out there.
