GridLock: Arrange Icons Anywhere
Gridlock is a powerful new tweak that allows you to arrange the icons on your springboard however you would like, with the ease of drag and drop.
If you're still using iBlank or have a theme that requires an odd layout, this is definitely for you. For theme designers this could also be a huge deal as you could now set up themes in a completely new manner. There are a ton of great themes that require a lot of management to get them to work properly, but with this tweak it could provide a completely new way of looking at how a theme can work and interact with it's counterparts, essentially making it that much easier to completely transform the look of your iDevice.
The app is fully compatible with Infinidock, Infinifolders, FCSB, Iconoclasm, and FiveIRows and more. However you will not be able to arrange any icons via iTunes for obvious reasons.
Check out GridLock in Cydia for only 99 cents.
You will be required to have iOS 4. Note it is not compatible with Infiniboard.
