Nokia has finished its development with Windows Phone and plans to reveal its first batch of Windows Phones at the Nokia World event, which begins Oct. 26, according to Andy Lees, Microsoft’s Windows Phone boss.

“Nokia will announce its rollout plans with Windows Phone, among other things,” said Andy Lees, president of Microsoft’s Windows Phone division. “[Nokia] made an evaluation early on, and saw our roadmap for this year and next year, and it decided to bet the whole company on Windows Phone based on that.”

The phone looks exactly like the MeeGo based Nokia N9, even the colors that the phone will be available in are identical.

The phone comes with a 3.7-inch touch screen and will be available in shades of black, blue, and pink. The specifications of the phone are not known. However if N9 similarity is any indication it will surely be a powerful device.

Microsoft’s Andy Lees also had this to say about Nokia:

“It made an evaluation early on, and saw our roadmap for this year and next year, and it decided to bet the whole company on Windows Phone based on that. We’ve seen that other hardware makers have seen this occurrence as an accelerant, which in turn helps both Microsoft and Nokia. I’m also excited about naming some new OEMs that will be coming onboard [with WP7].”

Sounds like more phone makers are interested in doing more with Microsoft’s mobile operating system. Stay tuned we will bring you with latest update.
