New day new Cydia app, infinifolders. Apple limited the amount of icons that you can add to a folder in iOS 4 to a maximum of 12. But thanks to Infinifolders, “which  is a tweak developed by chpwn” you are not limited anymore and you can add as many icons in a folder as you want. You can access the icon by scrolling up and down. You can purchase infinifolders in the Cydia store for $1,99 via the BigBoss repo and is only compatible with iOS 4.
