HTC Cavalier is an upgraded Dash (Excalibur)
Solopalmari got their hands on the latest Smartphone HTC are developing as the higher-end version of their Excalibur (S620), which is currently available in the States as the T-Mobile Dash. The new model is named Cavalier and slightly changes the design (see the pictures below) but adds many on the specifications part: high-speed 3G data UMTS/HSDPA that upgrades the current EDGE (still it is unknown if it would be tri-band 3G for world usage as it is with the TyTN (Cingular 8525)). Samsung 400MHz processor replaces the old Texas Instruments at 200MHz. The camera resolution goes to 2-megapixels from 1.3 for the Excalibur, and the microSD slot is now accessible on the left side of the device, instead under the battery cover.
Other features of the phone include QVGA landscape display, full QWERTY keyboard, Bluetooth v2.0, miniUSB and WiFi and relatively thin body similar to the one of the Motorola Q and the BlackJack from Samsung.
