I need some advice. I am currently shopping for a cell phone provider and I am don't want to get screwed into a contract with a phone that does not get coverage. I am thinking of going with Cingular which uses GSM. I am also looking into Verizon which uses CDMA. I will mostly use it in the Ann Arbor area, but will be traveling throughout the state since I just moved here. I hear Cingular is not very good outside major cities. Any validity to this? Any input would be greatly appreciated from fellow michigan oil junkies.
