There is an update for Five-Column SpringBoard (FCSB) to version 0.58-2. This is a good news to Jailbroken iPhone user especially for those who upgraded their iPhone to OS 3.0. I'm already installed FCSB to my iPhone OS 3.0 and its works very well.

Develop by Yanik Magnan, Five-Column SpringBoard is a MobileSubstrate extension that adds fifth column to your iPhone's home screen. Checkout my post on how to install FCSB via Cydia.

NOTE: FiveIRows GUI application can integrated with FCSB but does not works well with iPhone OS 3.0
