A few hours ago, Ryan Petrich pushed an update for Cydia tweak OverBoard, which should now be iOS 4-compatible and fixes some minor bugs. OverBoard is a tweak that gives you an Éxpose style view of all you pages so you can see all you apps at a glance. To install this update, fire up Cydia, tap “Changes” and press “Upgrade”.
Note: OverBoard supports WinterBoard themes, advanced customization and multiple activation methods (home button, SpringBoard icon, and pinch). The app also extends SpringBoard page limit.
OverBoard is available in the Cydia Store via ModMyi repository for $1.99
