Dolphin browser works as good as Opera but also allows posting in chat, forum, etc.
But it's far heavier. If your phose has a slow processor it doesn't work that good.
I am using the default web browser that comes with Android (my cell's OS) and id makes everything! Navigation is a bit slow, but you can post in hat room and leave a comment in matches, even more, match commentary is updated in real time and it doesn't need to reload the page everytime you pick a different tab.
If somebody uses Android, try andoid default browser, it works great.
