How to Install Game Center on iPhone 3G [Guide]

Apple released iOS 4.1 but without Game Center for iPhone 3G. In fact Apple completely denied the compatibility of Game Centre with iPhone 3G and what you will call it, a monopoly. But thanks to jailbreak which allowed us to enable and install the missing features on iPhone 3G like multitasking, homescreen wallpapers and this time Game Centre.

Before installing the Game Centre, you iPhone should be updated to iOS 4.1 and jailbroken. Head over to this post for complete instructions to jailbreak iPhone 3G with Redsnow.
