Ok, so I got an iPhone 4 about two weeks ago. I was expecting that playing games on this puppy would be pretty smooth. But alas, it is very laggy on some games. Now, normally this would seem pretty weird. But what gets me is my old 3GS runs games BETTER!!!! I tried playing black ops zombies and gta vice city and there both really laggy/ slow! Does anyone know what to do? Is my phone in a "break in" period. Please help me!
