Thanks for your info!
T-Mobile was not originally one of my GSM choices, due to being only in the 1900 freq. AT&T and Cingular are developing some 850 area's as well as using the 1900 mg freq, and I hope they will expand the 850 as time goes on. Also a friend is with T-Mobile, and she complains that she has to step outdoors to make a call, where I can call inside my house...for I like you do not have a landline. Also need to make sure it works a little of the "beaten path", for I travel inland sometimes. But then again, I have heard excellent things about T-Mobile's customer service. I haven't fully decided yet to leave CDMA or Verizon, for if I do decide to go GSM, I need to make sure the coverage is going to at least equal what I have now, and allow me other advantages...such as overseas travel, etc. I am going to continue to listen to people's opinions on either side and then will make my decision. Thanks again!!
