WebSockets and many other great features are now available across the iOS devices that are updated to iOS 4.2.

You can test your devices for WebSocket support and I just tested iPad and iPhone/iPods on iOS 4.2 and it is a go.

The update also adds some other excellent Safari browser features including:

• As mentioned, WebSocket support
• Accelerometer support
• Improved SVG and Canvas rendering
• Better Ajax

The new Safari on iOS 4.2 makes the iOS platform the current best html5 mobile solution for interactive apps and games in the browser. This should add some fun in terms of interactive web, games and better web experiences for iOS users.

• More on new features in iOS 4.2 Safari
• Test your browser for WebSockets
• Play with the accelerometer in javascript

We hope they add in WebGL support soon, there was mention of WebGLRenderingContext but not supported in browser yet.
