The guys over at Patently Apple uncovered an interesting patent filing from Apple revealing an accessory transceiver that could provide the iPod Touch with access to a mobile telephone network.

According the patent, this accessory transceiver could be connected wirelessly or physically to the iPod Touch. Not only it would work for an iPod Touch, but it also seems it would work with any mobile device, like a Blackberry, a camera, etc…

In some embodiments, the mobile device could also include an internal wireless transceiver that could provide access to a different mobile telephone network. Thus, using the accessory transceiver could allow the mobile device to access two separate mobile telephone networks.

Looks interesting. Complete details over at Patently Apple.
