Microsoft said it’s on track to launch handsets with Windows Phone 7 before the end of the year. In a blog posting senior VP for mobile Aaron Woodman said the new OS will be “well represented in countries around the world this holiday”. During initial availability, Windows Phone 7 will support the languages English, French, Italian, German and Spanish. At the same time, the Windows Phone Marketplace will support the buying and selling of applications in 17 countries: Australia, Austria, Belgium, Canada, France, Germany, Hong Kong, India, Ireland, Italy, Mexico, New Zealand, Singapore, Spain, Switzerland, UK and US. Woodman said this launch “is a fresh start for Microsoft’s mobile efforts”, where the company will focus on putting the user experience at the centre of the product. Microsoft has also released the first developer tools for Windows Phone 7, in beta, and started shipping preview devices to developers.
