This is a browser you can install on a Nokia Symbian phone. It has better HTML5 support than the default.

The HTML5 test site scores the browser as 286 (compared to 94 for the standard browser) out of 475.

The details are here.

Key things (in my opinion) are:

Canvas 20/20. 2D and Text drawing are supported.
User Interaction 0/36. Drag and Drop – No.
Web Apps 15/20. Application Cache – YES.
Communication 15/36. XMLHttpRequest (Level 2 No, but original is there).
Storage 15/20. Local Storage – YES.
Workers 15/15. Web Workers – YES. Shared Workers – YES.

Very promising (but still no drag and drop).

It's only fair to share...
