Different colour scheme: the two browns don't contrast well on my phone, making it hard to see where the sub 3x3s are. Otherwise, Kudos!

I like to play M-SuDoKu, thanks for it. I suggest two features: - adapt the size to high resolution phones, - position the cursor by tipping the fields on the board

Just downloaded this app. Loved it on my Sony Ericsson k550i. Works great with my Blackberry Curve 8310. I suggest to hit the BB button and select Menu. From there go to Input Mode and select numpad and joypad. Then you can actually input numbers on the board.
