Has anyone got Trapster running successfully on the SGS2? with warnings and voice alerts? I get no sound or warnings out of it. I have not signed up with a Trapster email/account as yet because I am tryialling it. I don't know if this is a limitation of the trial/anonymous version (when you start and hit 'Continue') ie. no sound or warnings just the map? I have tried unsucessfully to find out on the Trapster website? Dave
