Enable HDR and Game Center on Jailbroken iPhone 3G / 3GS running iOS 4.1

When Apple released iOS 4.1, it announced HDR photos for iPhone 4, and Game Center for iPhone 4 / 3Gs. So, iPhone 3G / 3GS users was not satisfied as much as other users with iOS 4.1 as they don't get HDR or Game Center, so, after the release of Redsn0w 0.9.6 to jailbreak iPhone 3G on iOS 4.1 and Sn0wbreeze to jailbreak iPhone 3GS on iOS 4.1, you can now get both HDR photos and Game Center on jailbroken iPhone 3G / 3GS running iOS 4.1 with "HDR/GameCenter Enabler" tweak.

  

There's nothing easier than installing this tweak and enabling HDR photos and Game Center which Apple completely denied the compatibility of this feature on iPhone 3G. Of course this tweak works only on iPhone 3G running iOS 4.1.
Note: This tweak is available on Modmyi repo, works only on iOS 4.1, and can be activated once installed via Winterboard.
