This is for iPod users running 3.1.3 and under who need to make folders. You don't need to download Categories. First, add source "http://repo.xsellize.c0m/" without quotes. Next, search for "iOS3 Folders" and install it. Reboot or whatever and wiggle the home screen icons. After they're wiggling, drag one icon over another and it will form a folder. To rename it, click the folder while it's wiggling and type whatever you want it to be.
