In under a week, Microsoft will hold its Windows Phone Summit. But to our delight, screenshots demonstrating key features of Windows Phone 8 have been leaked to the internet. The images allegedly show off Skype integration allowing users to make calls and video calls and initiate Skype chats, as well as a redesigned camera application allegedly called Lenses. A new data monitoring centre is also shown, similar to what is seen in the latest Android OS. There is also a brand new interface for the Nokia Drive 3.0 GPS application. Check out the images below, originally from Nokia Innovation.
