WPCentral recently reported that Windows Phone Tango (final version: build 8773) will be officially released in early June. This report has been confirmed by two different sources of the Microsoft whose name was withheld. Although the final version of the ROM from the Tango has begun to spread to the trial, Microsoft is rumored to postpone the originally scheduled release in April, so the operator can perform the test over its full potential, and Microsoft can target the release of updates in a more universal, such as Mango release.
It looks like in June we'll see a lot of your Windows Phone Tango released by vendors and operators. Just refreshing your memory, Tango is the OS that is optimized for your Windows Phone with low specs and only 256MB RAM.
