I Play The Game But To My Shame You've Left Me To Dream All Alone

Ok, who knows much about games for mobile (cell) phones?

I have a Nokia 7250i, which is able to run Java games. I downloaded Worms, which is supposed to have 5 weapons, 5 backgrounds and 2 game modes. Instead I have 1 weapon, 1 background and 1 game mode. It's almost like this is a demo version (I did pay money for it). Does anyone know if these things run differently on different handsets?
