The Evo 4G could be the first phone on Sprint to stop waves of subscriber losses as customers jump ship to the iPhone, the company's CFO Robert Brust said at an investor's conference late Wednesday. He hoped the Android phone would make sure Sprint "won't lose as many" customers and cast it as the first true iPhone rival the network has had. Brust was unusually derogatory towards the Palm Pre and saw it as a device to settle for instead of an iPhone rather than an active choice customers could make as an alternative.
