The SGP Ultra Thin is one of the better cases on the market which are currently available for the iPhone 4. In the package you have so much included for the money you are paying. First off all, you get the case of course. You have a Steinheil LCD film protector, a nice little microfiber cloth, a logo protection film because of the cutout on the back of the case which shows off the Apple logo and 10 pieces of LED Flash diffused reflection protector which should solve the flash issue, that is if you have any issues which is very unlikely.
It's a snap on back cover for your iPhone 4 but you will say, " Hey I've seen a similar case like this. Why is this one unique?!? " Well, first of all I haven't seen a case which is better fitting, I mean it fits perfectly. The cutouts, the form-factor and the overall feel of the case will remind you of the iPhone 4's original design.
One of the reasons I love this case is that it doesn't scratch easily but it's a fingerprint magnet. Also if you go for the black version, I think it will show the fingerprints more as well as the dust specks. It adds a little bit of grip but it doesn't add bulk to the phone so you can enjoy it's original design. More of the review after the break.
Another reason why I really love this case is because of the cutouts. They are perfectly position and nice finished. Now here's the best part of the cutouts, the side cutouts for the buttons is amazing. When you buy a case for the iPhone 4, you usually get either totally covered buttons or just one large cutout for all the buttons. This case has absolutely stunning round cutouts for the buttons, it has separate buttons for the volume and mute switcher. As every snap on case, it has a full cutout for the lower part, fully exposing the mic, the speaker and the connector.
The upper side has a big cutout as well, a generous cutout for the Sleep/Awake button, the 3.5mm audio jack and the secondary noise canceling mic. The cutout for the camera is quite big, it has a lot of room for the camera and the flash. If you still have flash problems besides this big oval cutout you have those flash diffusers which will solve everything. The only visible logo is on the lower back which you might mind at first but once you get used to it you will hardly notice it.
The interior of the case is covered with some kind of a film which I guess is supposed to protect the glass of scratches and scuffs.
