Today, at the Windows Phone Developer Summit in San Francisco, Microsoft provided details regarding the upcoming Windows Phone 8 operating system.

The next version of the mobile OS promises to provide deep integration with the Windows 8 operating system, meaning that the next generation of Windows devices, from PCs to laptops to tablets to mobile phones, should interact very nicely. Microsoft's keynote at the Windows Phone Developer Summit was exciting for app developers, too, as the new "shared core" between Windows Phone 8 and Windows 8 should provide a lot of benefits when it comes to cross-platform development.

Along with its "shared core" announcement, Microsoft announced new additions and tweaks to its next-generation mobile OS, including a revamped user interface, built-in Nokia Maps, support for multicore phones and MicroSD cards, and improved support for various display resolutions.
