Newsflash! Cingular had a contract with T-Mobile for GSM coverage up here. About three weeks ago, T-Mobile bailed out on the deal, and Cingular is now without GSM service up here again! The great news is (if you can call it that) Cingular can sell you a phone that will flip back and forth to GSM and non-GSM coverage ( it does it automatically) which will allow you to have service up here until next year, when they will completely do away with their non-GSM service. Reassuring, isn't it?
Face it - there's not a single provider that actually covers the entire area up here. No matter which service you choose - expect holes for a few more years.
