Hi,
HTML 5 is supported by Apple Safari and opera desktop browsers only. IE8 and Mozilla didn't have support yet. I hope the mobiles phones, which are presently available does not support HTML 5. You have to use HTML 4.1 or XHTML to
develop mobile web applications inorder to work fine in all types of mobile browsers.
Microsoft is planning to release IE9 browser which supports HTML5. One more thing HTML 5 is not approved by W3C yet.
NOTE: May be iPhone 4, supports HTML 5.
Hope it helps u...
