Are there any chipsets out there that could support both AT&T (1900) and T-mobile 3G (1700) frequencies? Since one of the main reasons for the merger is for spectrum, it seems that AT&T must be planning on utilizing T-mobile's spectrum in the future to improve reach and reliability, so it would make sense for them to provide phones that support both frequencies.

All of the T-Mo 3G phones are 850/1700/1900/2100.

I believe this is incorrect.

Many T-mobile phones support old GSM (EDGE) on 850, 900, 1800, and 1900, which overlaps with AT&T. But UMTS (3G) support is on bands 1700 and 2100, neither of which AT&T uses. 2100 is common in Europe.

Yes. Google Quad-Band phones.
