Following up from the guide we posted earlier, iOS 4.1 has now been released for general use. The update brings Game Center, Ping, High Dynamic Resolution photography and HD Uploads as well as bug fixes, a performance boost for iPhone 3G being the most notable. Game Center will not work on the 3G model, but will on a 2nd Gen iPod Touch. The update is available within iTunes when you plug in your iPhone or iPod Touch or click here for detailed steps on how to download ,
