If you’ve got a jailbroken iOS device that you can’t upgrade to iOS 5.1, then you may have installed Apple’s new iPhoto app unofficially. The problem with this is, the app only supports the iOS 5.1 firmware, and you’re likely to run into some compatibility issues that cause iPhoto to crash and freeze every so often.
But thanks to a new tweak called iPhoto501Fix, you can quash those bugs and enjoy a seamless (almost) iPhoto experience.
