B&N files application for new e-reader

US bookseller Barnes & Noble could be launching a new version of its nook e-book reader, after it filed an application with the US government.

Technology blog Gizmodo reports the retailer made a recent filing with the Federal Communications about a new e-book reader.

In the US, companies wishing to produce devices that use the radio frequency spectrum
must get authorisation from the FCC. 

Barnes & Noble already sells a 3G model of the nook, which retails for $199 (£130). The retailer began selling its own e-book devices in November last year. Among its features is the ability to lend e-books to friends, a web browser and an email facility.
