( Mobile-review ) - O2 operator has launched an HTC Panda-based communicator called XDA Argon. I'd remind you that the manufacturer itself hasn't yet made an official release of the model. The communicator works in GSM/GPRS networks (no 3G mentioned). Besides O2 XDA Argon is powered by Windows Mobile 5.0 Pocket PC Phone Edition instead of the latest OS version. Now the device is available online at the O2 store.
