Two Smartphone giants seem set to go head-to-head on a new front very soon, thanks to an upcoming iPhone app from industrial metal band Nine Inch Nails, and a rumoured U2 branded BlackBerry from Research In Motion.
NIN’s Trent Reznor is currently awaiting approval from Apple for an app described as "Twitter within the Nine Inch Nails network," according to Reznor's long-time collaborator Rob Sheridan.
