The top carriers are Verizon Wireless (CDMA), Cingular (GSM and TDMA), Spint/Nextel (CDMA/iDEN), and T-Mobile (GSM). There is no overwhelming favorite, although for # of subscribers, VZW and Cingular are 1-2, so that makes CDMA more popular, but by a nose.
Which one is economical? All depends on what you're using it for. Factors include international travel, amount of minutes you want/need, unique features (e.g., data, push to talk), and who you call and who calls back.

Your question is kinda wrong..
I think it should be. What frequency band is widely use in the US?
I think GSM is widely use now in the US. Because GSM is widely use all over the world now, any country you go to they use GSM exept South Korea and Japan.
CDMA is the old technology.. Verizon and Sprint uses it because if they shift now to GSM their market will crash..
Look at AT&T Wireless they shift to GSM their market crash and was bought by Cingular!
Hope this info helps..
