A new Apple patent application suggests the company is working on a wireless transceiver accessory that would allow devices such as the iPad Wi-Fi and iPod touch to access cellular networks.
Entitled “Accessory Transceiver for Mobile Devices,” the application describes a transceiver that can connect to a mobile device via either a cord or wirelessly, and could support functions such as telephony, SMS, e-mail, and web access, via a cellular, Wi-Fi, satellite, or WiMAX network.
In another embodiment, the device itself contains a transceiver, and the accessory is used to access a second network.
