A good while back around the first of the year, I saw a post from simon that was sent from his blackberry to k2joom.com before he updated the site. I imagine that he used the browser to do it.
Ive been watching this forum for about a year now, and have not seen what your looking for here.
There is a voting for k2 on this page
