iMovie 1.1 without iOS 4.1. The new iMovie requires an upgrade to 4.1, leaving us jailbreakers out in the cold.* The solution I played with is simple. SSH into your phone or use iFile. Navigate to system/library/core services and select the SystemVersion.plist. Open it and edit (<string>4.0.1</string>) to say (<string>4.1</string>).* Respring and the iMovie update should appear in your AppStore updates.* Enjoy!
