Windows Phone 8 codenamed 'Apollo' has been in development since 2011-- now according to a report, Microsoft has indeed released Windows Phone 8 to manufacturers (RTM) on September 14.
Which means, it's a testing time for carriers and handset makers to test and preload before the October 29 launch.
To confirm the news, LiveSino, has posted pictures (embedded below) of what appear to be Windows Phone team members "signing off" an RTM wall.
In the pictures is Terry Myerson, a Windows Phone Division Corporate VP, and his team members have signed off on the RTM signature wall.
Microsoft when asked said "had nothing to share at this time." Microsoft also continue to decline to comment on when Microsoft plans to make the Windows Phone OS 7.8 update available to existing Windows Phone users.
Windows Phone 8 OS will allow Microsoft to adopt cutting edge technology and heavily compete with Android and iOS in terms of features and hardware flexibility. The Windows Phone 8 OS replaces the Windows Embedded core with a Windows NT-based one. The latest operating system includes multicore support, NFC/Wallet support, removable Micro SD card storage (for certain phone models), encryption and secure boot. Windows Phone 8 will support two new screen resolutions-- 1280x768 and 1280x720, in addition to the existing 480X800.
