Well, I needed a case right now and I didn't feel like waiting till July for the bumper case so I cancelled the bumper order and got myself a Griffin case (Reveal). It has a clear hard plastic back and thin rubber around the sides with precise cuts for the buttons and holes. This case doesn't add much bulk to the phone and has a slim profile but that also means that it's not much protective and it may or may not prevent the iphone from shattering should the inevitable drop happen, but I've no doubt that it will still lessen the impact and I like that it keeps the slim profile of the iphone 4 intact. This won't be my main case and I'm waiting till more cases come out with more variety but till then I'll be very happy with this case.
