For some reason on my iPhone 3GS, my games, namely 3D, such as Chaos Rings, Heroes Lore III, Cops and Robbers, and Spiderman, are incredibly slow. I have a 3GS, latest update, and I tried cleaning the memory using the Memory Status app. I would like to know the problem and how to fix it. Thanks, and sorry for making you read all this. I am angry that I paid a lot of money for those and I can't play.
