HTC put built the 'phone so ultimately it's their say. The telecoms body in each country decides which parts of the spectrum are available for use for a given purpose, and the carriers decide how to use them.
At the moment the only phone which looks like it may support AT&Ts' 3G network is the Kogan Agora, it's specs state it has a 850/1900/2100 MHz UMTS/HSDPA trasceiver, so you may want to talk to them about testing it on AT&Ts network. The G1 has, according to HTC, the ability to support the "global" standard 2100Mhz band for 3G and the 1700Mhz band used by T-Mobile in the US. It does not, however, have the capability to support the 850Mhz and 1900Mhz bands that AT&T have used. The biggest problem is that some countries (namely the US and Japan) didn't follow the Interational Telecommunication Unions spectrum allocation recommendations, which means that the initial standard of 2100Mhz for 3G couldn't be used in the US because the 2100Mhz band was already in use for something else (and even after the US regulator freed some space there wasn't enough to support the number of 3G users the carriers were expecting). Hope this is useful, Al. P.S. frequency band differences isn't something new to 3G, even with 2G some of the US carriers were given the OK to deploy GSM equipment operating on the 900MHz bands which isn't in use elsewhere.
