Microsoft has invited the world’s technology press to a press meeting on October 11, in London.

It is expected that Microsoft will announce the Windows Phone 7 OS, as well as perhaps providing an actual Windows Phone 7 device, to test on location at the event.

It is still not clear which phone manufacturer that will be the first to show off Microsoft’s new operating system. But it appears that at least LG, Samsung and Sony Ericsson has Windows Phone 7 models in the works. The company will reportedly hold several launch events around the world on the October 21 release date.
