Met a friend today and I saw his iPhone 4. Without giving a second thought, I asked him what case he has on because it looks sturdy and nice. The next thing he did was something I wasn't expecting... he started the video recording on his iPhone 4 and after 5 seconds, he threw his iPhone 4 to the floor!!! I was like OMG! I thought it was an accident or something. Then, he picked up his iPhone 4, showed me that it's still recording! Everything intact and not a single scratch!
Otterbox Commuter for iPhone 3G / 3GS
I forgot to take a photo of his iPhone 4. The photo above is my iPhone 3G. Also, the Otterbox case you can throw around is the Otterbox Defender. The Otterbox I have on my iPhone 3G is the Otterbox Commuter series. Sturdy enough but, not as sturdy as the Otterbox Defender. See the video below.
