You’ll recall that a matter of months ago the Finnish mobile phone giant popped its netbook cherry with the Nokia Booklet 3G Now, if shadowy sources cited on the interweb are to be believed, a second device is in R&D already.

Alas, we’ve no word on specs or release dates as yet – although the smart money is definitely on it featuring Nokia’s Maemo OS. But check back here for updates and we’ll be sure to fill you in on availability as well as if and when it lands on mobile broadband contract deals.
