The rumours and hearsay are flying heavily through the blogosphere on this fine, chilly Monday morning. Engadget received a note from noted leaker Roc-A-Fella mentioning that Cingular are well on their way to releasing a BlackBerry 8710c. According to the Roc, several Cingular call centres “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.” Anyone taking bets on this botched release? I kid, Cingular. I kid.
