Yesterday Microsoft revealed the features for its upcoming Windows Phone 8 system.
Unsurprisingly, current Windows Phone 7 devices won’t be able to run Windows Phone 8. However the biggest “look & feel” upgrade is the change to the Live Tiles on the start screen. Thankfully this feature will be delivered to existing WP7 devices… as “Windows Phone 7.8.”
CNN.com has a good summary of Windows Phone 8 features.
