Internet Explorer 9 ready at midnight
The browser is expected to reach Windows Phone late this year through the mobile OS' Mango update, which also brings multitasking.
Microsoft considers the browser important for the sake of moving the web forward and has taken the unusual step of encouraging users to stop running IE6. Older versions of the app, 6 most of all, have at times been notorious for relying on proprietary web rendering code that pushed developers to either write special code or to risk losing the majority of web browsers. IE9, along with much lower market share than in the past, has moved Microsoft to follow rivals like Apple, Google and Mozilla into focusing on web standards.
