Microsoft employees 'sign off' on Windows Phone 8 RTM
 

Windows Phone 8 may not have a firm release date, but reports are flooding in that it's just been released to manufacturers (RTM) so they can work on their side of the equation: hardware production. According to LiveSino, pictures posted to Chinese social network Sina Weibo show members of the Windows Phone team signing a banner marking the milestone. In particular, Terry Myerson, Corporate Vice President of the Windows Phone Division, was caught penning his name alongside others. ZDNet's own sources corroborate that Ballmer and Co. have deemed the operating system fit to ship. With manufacturers seemingly taken care of, developers will be able to get their mitts on the WP8 software development kit in roughly two weeks.
