Just when I had thought I found the perfect phone...
An astute reader, Rob Currie from Redpoint pointed out:
Hi Martin,
ATTWS is replacing 850Mhz TDMA spectrum with 850MHz GSM spectrum and as a result the newer US targeted tri-band phones are 850/1800/1900. If you purchase a foreign tri-band then it's usually 900/1800/1900 - a huge loss with respect to coverage due to the better propagation of 850.That's why I went with the quad band v500/v600. I've run across a lot of people purchasing 900/1800/1900 tri-band phones for world coverage and in the process severely handicapping their home coverage without knowing it.

So I walked over to talk to our resident ATTWS experts in the telco group and did find out that my coverage on ATTWS is about half what it could be. This because my phone only connects to ATTWS cells running at 1900. Now with the Cingular network merger, they have inmarket roaming so I can use the 1900 Cingular cells as well. But all new GSM antennas at ATTWS are going to be 850. So the real killer phone for world coverage (including US) is a quad phone doing 850/900/1800/1900. Well off to e-bay....
