Another device has surfaced on the MWG web site. The MWg UBiQUiO 503g seems to have taken the place previously held by a placeholder for a device called the Xda Flame 2, presumably the Flame successor.
After looking at the specs, it appears that MWG has done nothing except add its own brand name to the device name. Like the UBiQUiO 503G announced back in March, it is powered by Windows Mobile 6 and an Intel 520 MHz processor and comes with 96MB RAM and 192MB ROM, quad-band GSM/GPRS/EDGE and tri-band WCDMA/UMTS/HSDPA support, a 2.4-inch QVGA display, 802.11 b/g Wi-Fi, Bluetooth 1.2 with A2DP, QWERTY keyboard, a 2MP main camera as well as a 0.3MP camera for video conferencing, and a microSD expansion slot.
Given that the UBiQUiO 503G has been available for a while, I suspect that the MWG version is either already available or will be very shortly.
