ESPOO, Finland and WASHINGTON, USA - A device codenamed Nokia RX-51 (Roxy) has been approved by US communications regulator FCC. It is highly likely that the "Roxy" could be the upcoming Nokia N900 Internet Tablet.

According to the specifications in the certification page, the RX-51 is said to include the WCDMA 1700/2100 bands, used by T-Mobile USA for 3G. The N900 would be Nokia's first MID with network connectivity options; the previous N800 and N810 were only able to connect to the internet via Bluetooth and Wi-Fi.

Quadband GSM, GPS, Wi-Fi, Bluetooth, and FM transmitter, a potential QWERTY keyboard, and a battery with 1320mAh of capacity are other features of this slididing internet tablet.

Previously leaked information shows that the N900, at 59.7mm x 111mm x 18.2mm, will be smaller than the N810 in terms of dimensions, and only slightly larger than the Nokia N97. It should also run on the Maemo operating system, based on Linux, which is currently used on both N810 and N800 - this system configuration can been hacked by end-users such as that Google's Android operating system can be easily installed and ran on Nokia's Internet Tablets.

The list of components revealed that the N900 will have a 3.5" touchscreen display with 800x400 pixels of resolution; 32GB of internal memory; an OMAP3430 CPU at 500 or 600MHz; a 5 megapixel camera with dual LED flash, autofocus, and Carl Zeiss optics; 1GB total virtual runtime memory; TV-out; and a full QWERTY keyboard that slides out, rather than tilting as the N97's keyboard.

The Nokia N900's release date was rumoured to round July 2009 for international markets and MEA (clearly delayed in this sense), August/September for the North-American region, and October 2009 for Europe. Price is yet unknown, but the N900 is clearly a high-end internet tablet, and should be priced accordingly.
