Game Center, HDR Enabler For iPhone 3GS, 3G iOS 4.1

For the unaware, Game Center and HDR Photos are two new cool features that come with the iOS 4.1 firmware. While Game Center has not been supported for iPhone 3G (even though it’s capable of), HDR Photos is not natively available on both iPhone 3G and iPhone 3GS.
For the adventurous, here is how you can manually enable Game Center on iPhone 3G and activate HDR photos on iPhone 3GS, 3G. We already have a Cydia app to enable HDR photos. Now a two in one free Cydia app HDR/Game Center Enabler has been released, to give you the features on your jailbroken iPhone.
