According to a leaked image posted by WMPoweruser, Microsoft is planning to release its Windows Phone "Tango" update to the world sometime in the second quarter of 2012. Tango is expected to be a software update focused around cheaper handsets for developing countries, but users in the U.S. should also be receiving the upgrade.
In addition, the same leaked roadmap claims that Windows Phone "Apollo" will be released sometime in the fourth quarter of 2012. Apollo is expected to be focused around high-end super phones and address the lack of business-oriented features in the current version of Windows Phone 7.
Microsoft released the first major update to Windows Phone 7 earlier this year in the form of "Mango," which brought general improvements to the mobile platform including:
- Improved live tile notifications (especially the People tile)
- Improved auto-correct on typing
- "Threads" is a new feature that combines things like text conversations, Facebook messages, Google chats, and more into one thread that can be read
- Users can now have one tile for multiple email accounts
- Email messaging has been improved for enterprise users with features like locked forwarding
- Calendar has been updated with Facebook event support
- Voice commands have been updated: now includes notifications over voice, allowing users to delete or read them
- Photos app updated with automatic tagging
- SkyDrive support and an improved Excel app
- Improved game tiles and Xbox LIVE integration
- Multitasking improvements
- Internet Explorer 9 with HTML5 capabilities
