The rumors that it won't work on AT&T's 3G (UMTS) being true would shock me. In order to support T-Mobile's 3G (UMTS) network, it would have to run on Cell, PCS, and AWS (850/1900/1700/2100) spectrums. Currently T-Mobile only supports UMTS on their AWS (1700/2100) spectrum, but that could change in the future. AT&T's 3G network runs on Cell and PCS (850/1900). They would have to intentionally disable UMTS on Cell and PCS in order to block out AT&T's 3G network, which would be extremely stupid considering that T-Mobile will eventually move UMTS to their PCS spectrum in the future.
"Intentionally disable" ? I don't think so. There are plenty of phones that get 3G on T-Mobile and not AT&T (And vice versa).
900/1700/2100 is a pretty common set up for T-Mobile phones. According to FCC documents, this appears to be the only frequencies the Nexus 1 has been tested on.
Really, the only reason this is an issue is because of the rumor Google will be pushing this phone unlocked through retail. I don't think this is true. I think it will be exactly like the G1.
In order for your first statement to be true, those phones would have to be told only to operate UMTS on T-Mobile AWS frequencies, which is an asinine strategy. The 900/1700/2100 might be a common setup for European T-Mobile phones. T-Mobile phones in the US are almost entirely 850/1900. T-Mobile operates almost exclusively on PCS (1900MHz) frequencies in the US.

Being that 850/1900 are AT&T's 3G bands, I think you might be confused. I just looked at T-Mobile's and HTC's websites; all of the 3G phones I could find operated on either 2100 or 1700/2100.
So it appears multi-touch is disabled on this device also? IIRC Google stated that Verizon wanted multi-touch disabled on the Droid but here's Google's first party blessed handset and it's also lacking multi-touch. Something's not adding up. We're past the point of oversight or third party objections.

All we have is a Google blog entry that specifically says this is a development phone to test new features, and a bunch of speculation.
