Rumor has it that BlackBerry maker, Research in Motion, and Cingular have begun the initial round of testing on the BlackBerry 8710c. According to Engadget Mobile insider, Roc A Fella, several of Cingular’s call centers in the US now have the device.

The new BlackBerry 8710c will have quadband GSM and a dual-band 850/1900 UTMS radio housed inside of a BlackBerry 8700 body.

There is no word on a release date or if Cingular will have a BlackBerry 8800 model out before the 8710c.
