Cingular uses both 850Mhz and 1900Mhz for GSM coverage.
You will be severely hampered in the coverage you receive with Cingular if you use a device that does not have the 850Mhz GSM band, such as the 7230.
Some areas of the country are still OK on 1900MHz devices, but I wouldn't recommend it. You could lose coverage down the road.
