'FolderIconRadius' Lets You Choose the Radius Amount of Your iOS 7 Folder Icons
If you want to have control over the radius amount of your iOS 7 folder icons, then check out a new free jailbreak tweak called FolderIconRadius
by iOS developer Quin Schurman.
With this tweak installed, you will be able to configure the radius amount for all of your folder icons on your Home Screen, as shown above. Changing the radius amount lets you make the corners of the folder icon as pointy or as round as you like.
FolderIconRadius adds a preferences pane to your Settings application where you can enable or disable the tweak on demand, as well as configure the radius amount that you want:
Whenever you make changes to the icon radius, you will need to respring. Luckily, a respring button is included in the preferences pane for you. You can enter a radius amount of anywhere from 0 to 33.
FolderIconRadius is compatible with iPhones, iPod touches, and iPads running iOS 7. If you would like to give the tweak a try, it's available for free right now in Cydia's BigBoss repository.
