Chess.com goes mobile?
But not on boards like Daily Puzzle, there only drag-drop is available.
I just loaded Opera Mini on my A900 mobile phone and was able to login and make a move. Was pretty cool. Only problem I had was the zoom in was too zoomed in. If there is a way to control the size of the zoom in box, this would work pretty good. Going to try to replace the browser on my WM6 now. I have a bigger screen on it (using Dell Axim v51). Which I really prefer if I'm going to be evaluating a position and making a move on the go. So far the default ie browser doesn't work too well.
