Safari on iOS 4.2: Much Better HTML5 Support, Accelerometer

Today, iOS 4.2 appears as a free update for every iPhone, iPod or iPad device. This release provides some major changes on HTML5 support, like WebSockets and Accelerometer support, new events, print support, new JavaScript data-types and better SVG support.

Apple didn’t update yet Safari documentation to reflect new APIs in iOS. This information is based on JavaScript research and testing over Safari itself.

iOS is a “closed” platform, right?
