I am a former owner of a Verizon Treo 600. I left Verizon because their coverage in my area was spotty. I switched to Cincinnati Bell Wireless - which has always run on the AT&T network (now Cingular). CBW did not have Treos when I switched, and they are GSM anyway, so I went without for a while.

I just picked up a used unlocked Treo 600. Am I correct in assuming that it should work if I just put my CBW Sim card in it? Anything else I need to do? Is there a FAQ or somethign somewhere I should be reading?

Thanks in advance for your help.
