Nokia Corp. is getting ready to launch its first smartphones based on Windows Phone 7.5 "Mango" operating system. It is most likely that the company will show the handset at its Nokia World  event in late October and will start selling it towards the end of the year. The company has already started to prepare ads for its Nokia 800.

Keeping in mind that the first WP 7.5 "Mango" is generally a rush project at Nokia, which only made decision to adopt Windows Phone as its primary operating system for smartphones earlier this year, the information that is circulating about it is not completely clear in many ways, but it is widely believed that it shares a lot of technologies with the Meego-based N9 flagship, but fully complies with system and minimum equipment list of Windows Phone operating system.

What we do possibly know about the first Nokia Windows Phone 7.5 "Mango"-based smartphone from Nokia - the Nokia 800 - is that it sports a curved 3.7" AMOLED multi-touch display with unknown resolution and does not sport any hardware buttons on the front side. The handset is presumably powered by Qualcomm Snapdragon QSD8250 (up to 1GHz Scorpion ARM Cortex-A8 core, Adreno 200 graphics processing unit, 720p video, up to 12MP camera, integrated 3G, GSM, GPRS, EDGE, HSPA support and so on) system on-chip, sports 8MP camera, GPS navigation and other innovations.

Pocketnow.com web-site has managed to obtain the first Nokia 800 ads* that depict the smartphone itself and show off the Windows Phone 7-style pattern that looks more like a disco-style one. The two ads obtained by the media resource emphasize broad set of capabilities amid high responsiveness of the handset. It is unknown, though, whether the banners are the legitimate and final since the handsets on both have differences.

Based on unofficial information, Nokia is preparing several smartphones, including code-named Sun (presumably with with 12MP camera and dual-core SoC), Saber (single-core SoC, 8MP camera), Sea Ray/Searay (with multi-touch screen) and something featuring a QWERTY keypad smartphones based on Windows Phone 7.5 "Mango" operating system for the "initial" lineup release.   In total, there are twelve Nokia Windows Phone 7 devices planned to be released in 2012. All of them are likely to somewhat resemble Symbian-based products, but should naturally offer clear advantages over the platform that is fading away.   The actual code-name of the Nokia 800 is unknown. Based on unofficial specifications and design, it is clearly not the Sea Ray handset shown back in June, 2011, but is likely the Saber.

Nokia World 2011 event takes place in London, the UK, in October 26-27, 2011.
