This might not be as good a deal as it first appears, so watch out! While the phone is cheap, if you buy it from Cingular, you are locked in for 2 years and must have a minimum plan of $40 a month, plus $45 a month in Blackberry service charges. That's $85 a month!T-mobile offers what appears to me to be a far more competitive plan including voice and Blackberry data for $65. Admittedly, they don't sell or officially support the 8700c, but if you can get an unlocked one, it'll work.I'm not sure if Cingular offers a service superior enough to justify the additional price, but am currently using T-mobile and considering switching, so I'd appreciate any comments/advice!
