It works in portrait and landscape mode, you can select backgrounds and of course swipe gesture to control playback. No two and three finger swaps though. You don't have that "made for a smaller screen" feeling, so that is the good part.
iGesture is the best touch/gesture based controller for your iPhone. Now you can continue jogging and simply swipe the screen to have complete control over all of your music and audio. Its also perfect for driving, riding a bike or motorcycle, love making, and a number of activities where you simply can't or don't have time to look at your iPhone.
