As we inch closer to the Nokia World event in London at the end of the month (October 26 to be precise), details are starting to trickle on Nokia’s first Windows Phone 7.5 “Mango” device. Pocketnow and GSMArena have supposedly come across ads for the device that carry the Nokia 800 moniker.

It would suffice to say that the device codenamed “Sea Ray” hasn’t exactly been Nokia’s best-kept secret. In fact, back in June, Stephen Elop, Nokia’s CEO publicly showed off the device during a presentation. The device takes after Nokia’s MeeGo-toting N9 with a few changes.

The full curved glass façade of the N9 has been replaced to accommodate three buttons, while plastic unibody enclosure remains unchanged for the most part. As you might recollect, the N9 isn’t exactly a budget phone; with a suggested price of around 475 EUR for the 16GB and 534 EUR for the 64GB variants, it’s sitting comfortably in the premium segment. So if the Nokia 800 has to succeed as Nokia’s first Windows Phone device, the price is definitely going to be an important factor.

While the ads themselves shed little light on what’s inside, folks over at GSMArena seem to believe the device will pack a 3.7” WVGA (800x480) AMOLED screen (down from the N9’s 3.9” screen) and a processor running at 1.4Ghz (possibly a Qualcomm MSM8255 with an Adreno 205 GPU).

As promised by Mr. Elop, it looks like the Nokia 800 is all set to launch just in time for the lucrative holiday season.
