Published: 03 Dec 2008 10:00 GMT
O2's Xda heritage is as old as Windows Mobile itself: O2 was an original hardware partner for Microsoft at the launch of Windows Mobile, and in the UK the network operator has always maintained a strong line of devices.
However the Xda Zest is a first. It's the first Xda to be available on O2's Pay & Go tariff as well as on Pay Monthly. It will be free on some Pay Monthly tariffs, and will set you back £249.99 on Pay & Go.
