Normally, when we get tips about the outlandish, we kinda chuckle a bit and put them aside -- except for when it's one of our favorite insiders, Roc A Fella. He's reporting that several of Cingular's call centers in the US now have the BlackBerry 8710c and the initial round of testing has begun. Roc says the device has a quadband GSM and dual-band 850 / 1900 UMTS radio built on the 8700 series body. Stay tuned for the pics!
