Sound the new mobile operating system klaxon. Microsoft has ZDNet reports.finished , and has shipped it to manufacturers to start playing with,
This is known as the release to manufacturing (RTM) stage. So what happens now? Well, it's a simple case of those device makers testing it out on their shiny new handsets and making sure everything's hunky-dory before getting it into the hands of us, the great phone-using public.

There's no official word from Microsoft yet. When ZDNet contacted the Redmond-based company for comment, it replied it had "nothing to share at this time".
Microsoft is set to launch Windows Phone 8 on 29 October, withexpected to be available shortly after. It originally planned to launch in early October, along with Windows 8, but things slipped. So now -- fingers crossed -- everything looks to be on course.
Windows Phone 8 will face stiff competition from the iPhone 5, which goes on sale in less than a week, and . And of course Android Jelly Bean, which will be a few months old by the time Windows Phone 8 launches.
Microsoft will vie with BlackBerry-maker RIM for third place on the mobile podium. RIM will launch BB10, so we could have quite a fight on our hands this winter.
