Some of the best tweaks to be developed are plain simple tweaks, that are useful. GridLock is a great example of one of these tweaks, and what GridLock actually allows you to do is position icons on your SpringBoard in whatever fashion you wish to (breaking the iPodTouch/iPhone’s rows and columns restrictions).While all the details about this tweak are yet to be discovered, by looking at the image you can clearly tell this tweak will give you free range over icon layouts. The minds behind this tweak are Chpwn and p0sixninja, who just announced this tweak earlier today.
This tweak will be available in the Cydia Store for most likely around $1, and will work on the iPod Touch and iPhone. We will need to wait for more details, but we will keep you updated. Stay tuned.
