Following on from the success of the Orange M500 (HTC Magician) - Orange have announced the Orange M600 which is their variant of the HTC Prophet device.
I somehow missed this announcement but one of my colleagues pointed to it at CoolSmartphone. http://www.coolsmartphone.com/news2163.html
The device carries Windows Mobile 5.0 and Orange estimate standby time of 180 hours (7 and a half days!) as well as talk time of 5hrs.
