On June 20 2012 Microsoft revealed the next version of their mobile operating system. Windows Phone 8.
WP8 shares code with Windows 8 (for desktop), which gives WP8 support for multi core CPUs, 720p screen resolution, microSD cards (finally!), NFC and more.
The sad news is that today’s Windows Phone handsets running WP7 won’t be upgradable due to this. That’s why my headline says beta period over. That said, owners of Windows Phone 7.5 handsets will get an update to Windows Phone 7.8 which brings the updated start screen from WP8.
WP8 will get OTA (over the air) updates, dropping Zune all together. Other features: IE10, Wallet, in-app purchases, Nokia Maps with offline maps and turn-by-turn navigation for all WP8 handsets.
