Huawei showed off some neat concept phones this year at CeBIT, including a handset with an integrated USB connection at the handset's top that eliminates the need for any data cables or adapters (although, we'd like to see that plugged into a new laptop with relative ease). Anyhoo, Huawei also announced a new handset with an external battery only that makes a battery swap very easy as well as, umm, somewhat fashionable with that battery dongle hanging off your phone. The third Huawei concept sticks a Bluetooth headset right on the side of the handset so that the pair never, ever miss each other. We're not fans of ringing phones with no Bluetooth headset in sight either, Huawei. Kudos.
