Most Windows Phones have received the update to Mango, bringing multitasking and improved performance, so now we’re looking to the next update in Tango and then Apollo.
A leaked Microsoft document from October is stating that Tango will be released first, sometime in mid-2012, with Apollo following closely afterwards in Q4.
As for Tango, it’s meant to open up the platform to cheaper handsets, allowing vendors like Nokia to debut low-cost Windows Phones with smaller screen resolutions and slower chipsets to compete with the proliferation of Android devices devouring the market. Tango should also bring NFC support to new Windows Phone devices.
Apollo should follow afterwards for the higher-end market, presumably bringing full-scale LTE support to the OS along with higher-resolution displays. Also in tow is better business and enterprise support. At the moment, all Windows Phone devices are limited to a 480×800 pixel display resolution, which was fine in late 2010 but is nudging up against limitation now.
While the release schedules may not be set in stone, we have a good indication that the update cycle for Windows Phone is not slowing down any time soon, and that existing owners should receive the new versions for at least two more cycles.
