Nokia is to have another go at convincing customers they need a tablet PC in their house according to spy shots that have turned up on the internet.

Called the Nokia RX-51, the handset, which looks like an XL version of the N97 just released are from an Indonesian website claiming to have got their mitts on a prototype.

According to the forum where the details were first posted the new model will have a screen resolution of 800 by 480 pixels, 5 megapixel camera with Carl Ziess lens on the back, slide out qwerty keyboard and Wi-Fi. It will run on an OMAP3 ARM Texas Instruments chipset. A SIM card slot also looks to be present.

Not surprisingly considering the history of the company's N800 and N710 models it will run the Linux Operating System based on Maema 5.

Nokia is expected to launch a range of new devices at Nokia World in September.

Pocket-lint's own sources within Nokia have previously told us that the 2009 roadmap shows some interesting devices rather than just more handsets.

Could this be launching next month? Pocket-lint will be at Nokia World at the beginning of September bringing you the latest news as it happens.

Stay tuned.
