These two phones are variations of the HTC Artemis. Though they have different casings, they're identical inside. They are Windows Mobile 5 Pocket PC phones and the HTC P3300 is sold unlocked while the XDA Orbit is offered by O2 in Europe. Features include a very compact design, internal GPS, quad band GSM phone with EDGE for data, a 2MP camera, WiFi and Bluetooth. We got a hold of both models for this review.
