Speaking of Windows Phone updates and rumors, our friends over at Mi Movil Windows have confirmed with two sources that Windows Phone Tango (finalized as OS build 8773) will be released officially at the beginning of June. (We've been told who the sources are but have been asked to not name them).

Even though ROMs of Tango have been floating around for awhile (and we've seen some for the Lumia 710 as of late) Microsoft reportedly pushed the April time-frame for release back to June so that more operators could finish testing and Microsoft could target a more universal roll-out, much like Mango. This becomes self-evident when you realize that no Tango updates have happened yet, even though the ROM has been finalized.

Of course if true, this won't mean we'll all get Tango the same day, let alone the same week. Instead what we could be seeing here is a rolling update where various regions and carriers will release over an extended time-frame.  This sounds a lot like the Mango-update which took roughly two-months to reach nearly 90% of devices. The difference here is the fact that Tango is a far cry from those 500-new features we saw last year.

Windows Phone Tango is expected to be optimized for 256 MB devices for emerging markets, feature enhanced MMS capability and other under the hood optimizations.

It will be interesting to see if AT&T, who have gone on the record twice now, will be taking advantage of this extension to also roll out this Tango update for current devices. The timing seems about right.
