Does iphone OS 4 support Web socket?

I am working on an investigation se开发者_运维问答e how web sockets is supported in browser. Firefox nightly build : Yes. IE 9 Preview: No.

Can someone help me check if it's supported on Iphone OS4? Please check it on following page: http://jimbergman.net/websocket-web-browser-test/

Thanks in advance.
