Just received an e-mail broadcasted from O2 with these news:
"O2 Asia will not be deploying the Pocket PC 2003 upgrade. The Pocket PC 2003 upgrade is subject to the original design of the hardware and the level of integration of the device, particularly between the phone and pda functions. The O2 xda was not designed to support Bluetooth and Wi-Fi and therefore could not take advantage of some of the most important feature upgrades inherent in Pocket PC 2003. After careful evaluation of the costs and benefits and the relatively low impact on the user experience of the current xda version, we have decided not to deploy this upgrade. We are however pleased to announce that we will be introducing significant new features with another upgrade which will include the wireless modem, SIM Toolkit support and the SMS caller ID fix."
