Incase Leather Sleeve for 3G(S) on iPhone 4. I haven't seen/read of any sleeve and clip cases for the iPhone 4, so thought I'd share my experience. I had this for my 3GS and though I'd give it a try on the 4. I put it to good use before I created my own 3GS CandyShell and Ivy Skin Quattro Clip 'home-made combo'. This sleeve seems like it "almost" fits like it was made for the iPhone 4.
