Well there is the Triband SE K790a with both the 850/1900 needed by Cingy. If you are traveling overseas and really need the extra 900 band then there is the QuadBand Nokia N73.
Nope. Doesn't need QuadBand or even triband for that matter. Cingular justs uses two band 850/1900 so all you need is Dual Band. The other two band 900/1800 are used in other countries.
Does SE 790a come from Cingy or does only come unbranded? And if so would I have to get someone to load Cingy stuff on it to use all of there services?
that would probably be a good idea since you could even get it through cingular...although unlocked is always better and you can find it for around $200. it has a good camera too
