We have already seen a 5 row and column hacks for the iPhone. But on the iPhone it only gets bigger and better. Now we have Six Rows hack for the iPhone via Cydia. The app is a simple hack, and it does the job pretty well and works very smoothly.
But there are a few problems while using this tweak. Since it expands the iPhone springboard to six rows, the icon names cannot be seen (specially the ones at the top). Also, there is no way you can deactivate this either than deleting the app via Cydia. On top of it makes the iPhone look messy and it is very difficult to find your apps. Instead of this tweak, I prefer using Categories or even Fivel Row.
