The MOTORIZR Z8, Motorola's recently announced UIQ powered multimedia smartphone, will be climbing Everest in the company of Mark Baber as part of a Motorola sponsored expedition to make a phone call from the top of the worlds tallest mountain. The Z8 will be available in shops towards the end of May.

The call has been made possible by the installation of a new cell tower that has line of site visibility from the top of Everest. 

The Telegraph is running a competition to join the expedition at base camp, more details are available here.
