Yeah, I used to and even downloaded games from my network providers but now, I don't anymore... though I like puzzle games like Maya and something like bejeweled blitz...
YES , I love mobile phones games, It is nice to pass the boring hours in day. I daily download games from http://mobile-phones.com.pk/softwares/games/ it is good mobile game store..
I play dungeon hunter hd. Downloaded it for free, because of a special 1 day offer. I really like it. Looks very good on my samsung galaxy s.
