With its Nokia World convention just days away, Nokia has become a leaky cauldron, seemingly spilling more beans by the hour.

The latest leak is a supposed spy shot of the new Nokia Sabre, a second Windows Phone 7 handset that is different from the Nokia Sea Ray or Nokia 800 - both of which we’ve also seen in recent days.

"The phone in this image is allegedly a prototype of the upcoming Nokia Sabre Windows Phone we've been hearing about straight from Microsoft's mouth," reports Pocketnow.com.

According to the source, Sabre features a 1.4GHz processor (much like recent wave-two devices), 1GB of RAM, a 3.5-inch WVGA screen, 5-megapixel camera and a price tag of around 300-350 EU (around $410-$480).

The latest leak comes after we saw reported press shots of the Nokia 800, complete with the standard three back, home and search buttons and sporting black, blue and pink cases.

Pocket-lint will, of course, be in attendance at Nokia World itself, and will bring you all the latest news, first impressions, pictures, interviews, features and much more.
