Microsoft has tried to push standards with its mobile Internet Explorer browser, but unfortunately the wider web largely develops specifically for the webkit rendering engine and the iPhone. Twitter and a number of Google web sites do not render correctly in Windows Phone, but Microsoft thinks it has an answer. With the upcoming Windows Phone 8.1 Update 1, Microsoft is tweaking its mobile browser to better support sites that were designed for an iPhone. The approach means Microsoft is adding non-standard web platform features, but the result is a much better experience for Windows Phone users.
