In a pile of new Apple patent applications released today, one surprise stood out: Apple is working on an external transceiver that would turn an iPod touch - or any mobile device, from a media player to a game console - into a full-featured cellular phone. The patent, called "Accessory Transceiver for Mobile Devices," was highlighted by Patently Apple today. In addition to giving calling services to an iPod, the patent also details how the transceiver could be used to connect an iPhone to a different cellular network, specifically referencing a CDMA network like the one used by Verizon in the US.
