GSM frequency bands in the USA

[Nick]

Hi folks,

A change of tone for the list, for now.

I'm going to the USA soon, and would ideally like to use my GTA02
there. It is a European 900/1800/1900MHz version (I presume - I
bought it 2nd hand - is there an easy way to check?). Can I just use
any network in the USA, and it will just register with the 1900MHz
band and all just work? [0] implies that would work, but [1] implies
it may depend on the area of the USA, and I lack the knowledge to
readily figure it out.

Any clues?

Thanks,

Nick
