BriefMobile - How about another LG device heading to Sprint? We got a full frontal photo of the unannounced LG LS860. Known internally as the “Cayenne,” this device is basically an LG Viper variant with a QWERTY keyboard thrown into the mix. As you can see, there is indeed a 5-row keyboard and three capacitive touch button on the front of the device. The device will also sport the same exact 4-inch WVGA IPS screen and 1.2 GHz dual-core S3 processor.
