Mobile phones in space, Potentially lowering the cost of spacecraft design? Options

[jasedm]

An interesting mission outlined here proposes to blast a high-street mobile phone into orbit, to determine whether its processing power would be adequate to control a satellite in orbit.

Assuming the components within an ordinary handset can survive in space (it will be partly shielded by the satellite's casing) this might have appreciable effects on cost for some unmanned missions in the future.
