I ordered my Zagg IS about a week before the iphone 4 release. Signed up for the iPad contest and got a 40% off code. I made a custom back skin and ordered the full body IS and only cost me $27 including shipping for everything. I really wanted the white iPhone so I figured this was the next best thing. There is a tiny bit of orangepeel but the skin seems very durable. I have used the Zagg for mine and my wifes 3GS and I never had problems with it peeling off until about 6 months of it being on the phone. I had the coupon so I figured I might as well get it because I really wanted a skin for the back. Most likely will try the Phantom carbon fiber full body skin next.
That looks pretty sweet
