A major international retailer today published details about a previously unannounced BlackBerry with a clamshell form factor. The 8200 series contains the same features as Research In Motion’s Pearl 8100 series, including a SureType keyboard, trackball navigation, 2 megapixel camera, memory card slot, and quad-band GSM. An 8210 variant includes GPS, while the 8220 sports Wi-Fi instead.
