Microsoft's Windows Phone Mango Commercial Release 2

Earlier this week Nokia announced that their high-end phone, the Lumia 900 runs a newer build of Widows Phone called Mango Commercial Release 2. According to an article in the official Nokia corporate blog this new operating system is not the next Tango 1 OS which is supposed to be on devices that will launch in the first half of this year, but just a name for the Windows Phone build 8107.

Microsoft officials confirmed this week that Mango Commercial Release 2 is just Mango plus the 8107 service release. (The 8107 release is the bunch of Windows Phone fixes anchored by the “disappearing keyboard” fix.)

Microsoft officials said late last week that the company had delivered the 8107 service release to its carrier partners and that it would be up to them as to when, how and if they rolled it out to existing Windows Phone customers.
