MetroPCS announced on Thursday that it will be the first carrier in the US to offer Screen-it, a wireless caller naming service. Screen-it basically brings mobile callerID up to land-based standards – it allows you to see the name associated with an incoming phone call, even if that name is not in your address book. The new service will be powered by TARGUSinfo, the company that already provides callerID service for 75% of U.S cable, telephone and VoIP companies. The Screen-it service will be available starting October 2008 and will be included with select wireless packages or as an enhanced option available to add a la carte on other packages. No pricing details for the a la carte option were released.
