That's odd. Other quad-band phones are sold publicly in the US by 
high-profile sellers. See for example 

I imagine that any multi-band phone will listen on all its frequencies 
before it tries to register, and will therefore only transmit on 
frequencies that are in service in that area.

That said, I wonder why they (FIC and/or the FCC) didn't put the lower 
frequencies (850/900MHz) in the approval?
