Ok my question is, is AT&T all 1900 GSM or 800/850 also. And in what markets is AT&T 1900 GSM (in FL, GA, SC, NC, VA and DC is where i would need to use the phone)? Well when I go to the nokia website and look at the phones features is says is has GSM 1900 and AMPS. I don't understand how can i get a GSM plan and have my phone run on AMPS when GSM is not avalible. Can i request this as a service or not? Thanks for your replies, Sprint PCS 411 Well the Nokia 5190 is set to Tmobile at the current time I want to reset it (unlock it) so it will be on the AT&T Wireless or Cingular (which ever will be better in the long run) 1900 GSM network. I think AT&T is a PCS provider making them strictly 1900 and Cingular is 850 (and maybe some 1900). So i would like to have my phone unlocked to AT&T Wireless. Therefore it can roam on the 1900 GSM Cingular network as well as the AT&T AMPS and AT&T 1900 GSM network. So i need the IMEI for the Nokia Thanks!!!
