What do you do after a Mango? I usually sleep, but Microsoft has decided to Tango. Before Windows Phone 8, a major update similar to Mango (maybe, that’s why the name) will be released, say DigiTime’s sources. This is in with accordance to the rumors that Microsoft would be providing a major update to the OS every year. Furthermore, news has been leaked that Microsoft is already signing license agreements with OEMs, Compal being one of them. Compal is the company that is rumored to be developing Nokia’s and Acer’s first WP handsets.
