Not in the U.S.

The GSM carriers in the U.S. are still in the process of migrating away from TDMA networks. Some, like Cingular and T-Mobile have truly crappy networks. If you want GSM, stick with AT&T.

Nokia and Siemens GSM handsets r001, Moto drools. 90% of CDMA handsets use Qualcomm chipsets, so go for a good manufacturer, like LG. The vx6000 camera phone rocks.

Verizon has better coverage in the U.S., but your phone will only work in the U.S., Canada, Korea, Japan, and South America. If you travel to Europe, you want GSM.

T-Mobile is all GSM, no TDMA. But they have the thinnest coverage anyway.

I have Cingular & my service is great.

For whatever reason, I have really liked my T-Mobil coverage. My family has verizon and even though they have more expensive phones, they go on the fritz more often and get bad signals more than I do. We are in a major urban area, however. I've been reluctant to leave T-Mobile to join them on their family plan.
