I have an HTC One V in addition to my iPhone. One thing I love about it is the camera application. It has two buttons: one to capture a photo, and another to capture a video.
I love that you don't have to toggle between them and wait a second or two while it switches. That second or two could cause me to miss the funny things my kids are doing at that moment.
Is there a jailbreak tweak that brings this same sort of functionality to iOS?
