I am wanting to purchase an iPhone sleve for my iPhone 4. I know not many (if any?) cases are out for the iPhone 4's yet, but I'm guessing that any of the popular brands will come out with iPhone 4 cases soon after release. I'm wanting something simple and thin that I can simply slide my phone into in order to minimize scratches. I love the look of my iPhone and so I don't want to ruin it with a bulky and ugly case... I just want something to slip the phone into. Suggestions?
