Microsoft is getting ready to release its major "Mango" update for Windows Phone 7. The update is scheduled to launch alongside a new batch of smartphones later this fall from various smartphone makers that will have the Mango update powering the devices. However, there have been rumors popping up in the last couple of months of yet another upcoming update to the operating system - code named "Tango". Little is known about this update but ZDNet is now reporting more info about Tango via unnamed sources.
The article claims that the Tango update could in fact be split into two such updates to the OS. The article adds that both are supposed to be released sometime before Windows Phone 8, code named "Apollo". This will be the next major version of the Windows Phone OS that's currently believed to be scheduled to launch in late 2012. As far as Tango is concerned, the article claims, again via unnamed sources, that Tango could be a version of the OS that's being made for cheaper versions of Windows Phone devices, perhaps targeting the large Asian market.
The same story also links the Tango update to Nokia's launch of its Windows Phone 7 smartphones. It's not clear what they might have in common since the first Nokia phones with Windows Phone 7 are expected to come out using the Mango version of the OS.
