Or, if you want to give the whole "social" scene the miss, and just get games, you can go to MobileRated.com - no login/registration. What does everyone want my email address, and why does everything think they're a new FaceBook?
You know, I just don't get Cellufun. I don't want yet another social website, I just want to find games... I like MobileRated.com because there's no login/registration, you don't have to give them your email and risk spam, you can just go there and download whatever you, totally free. Also, they seem to have very good quality control (Cellufun too), unlike a lot of other sites.
