I've noticed that the games I have been downloading from the internet primarily don't save (if there is even enough gameplay to warrant saving...). Could anyone tell me how to 'fix' this or how one can tell whether or not by the version number perhaps whether it will save or not?

I know I shouldn't complain as I haven't paid for nearly all the games on my mobile, but it would be nice not to have to start from the beginning everytime I start one up. :|
