Let's face it, some jailbreak tweaks are purely cosmetic. Whether you like to change things around because it looks cleaner, feels cooler or it's simply different, there are plenty of home screen mods to go around. One tweak makes a basic change to the look of folder icons on your jailbroken iOS device. Normally iOS folders show a 3x3 grid of app icon thumbnails when there are 9 or more apps inside.
The tweak 2x2 Folder Icons does exactly what it sounds like it does. Every folder on your iOS device that has more than four apps inside will display a 2x2 grid of icon thumbnails. This results in a clean, fresh look on the iOS home screen, with plenty of space around the edges of folders.
Once installed, navigate to Settings -> 2x2 Folder Icons -> 2x2 Folders Layout -> OFF to switch your folders back to normal. You'll have to restart or respring before the changes take effect, and developer Surenix provides a convenient Respring Now button right in the settings. The 2x2 Folder Icons tweak takes one element of the complete ayecon WinterBoard theme ($2.99) and makes it stand-alone. The ayecon theme uses smaller home screen icons than iOS normally uses, so the 2x2 format was originally designed to accommodate this change.
2x2 Folder Icons is available on Cydia from the BigBoss repo for $0.99. Check here for instructions on how to jailbreak iOS 6.x with evasi0n. You can also find out how to purchase and install Cydia tweaks with this guide.
