Sony said it will add chat services, Internet telephony and video-to-video communications to its popular PlayStation Portable game unit, an upgrade the Japanese company hopes will transform the PSP into wireless multimedia communications device.
Sony said Wednesday it had struck a four-year deal with British Telecom to provide these and other services on the PSP. The new units are scheduled to be shipped by the end of the year and owners of existing PSPs will eligible to receive an upgrade for these services.
