There was a talk about Microsoft's plans on the launch of its updated Windows Phone version Mango, on September 1st. This was a rumor, says Microsoft's Joe Belfiore through twitter. The OS being released at the beginning of next month would make us feel that it requires IFA 2011 for the upcoming version in Berlin and also this will give us an advantage over Apple iOS.
