Hi folks.
I have an AJAX application that is now supposed to run on mobile

I have been told that the most significant players are symbian os and
palm os.

Does anyone know if palm os/Symbian os default browsers support

1) javascript
2) XMLHttpRequest object (asynchronous http requests)
3) some minimal form of CSS - cascading style sheets
4) DOM (some form of getElementByID/innerHTML and friends).

Thanks in advance
