BlackBerry enthusiast site PinStack posted an image of a Cingular ad for the upcoming BlackBerrry 8700c. While we can’t be sure it’s for real, the amount leaking around the 8700 makes it a sure bet even if the ad is a fake.

Specs of the BlackBerry 8700c include:

• Quad-band GSM plus EDGE high-speed data
• Bluetooth
• 320 ร— 240 screen
• Thinner design than past models

PinStack notes a launch party for the device is planned on Tuesday night. According to the posted image, Cingular will charge $299 for the 8700c.
