The hybrid silicone Hard Case from kwmobile is almost ideal for the iPhone4. Almost, because the recesses is for the charger plug the iPhone to open a bit cumbersome and the original plug is too thick for the actual opening. But if you handiert with caution, then it works without major problems. Otherwise, the protective sheath is really great, because it wraps around the phone and therefore the edges are covered. The mesh design is also an "eye-catcher" and protects again all around. Buy recommendation with a great price, if one accepts the small restriction.
