I have had a Survivor case for my iPhone 4 since it came out from Griffin Technology. I don’t use it much during the summer around the office, but it is a must have for the winter or when I travel. Now on my iPhone 4s, the case protected my iPhone 4 last winter when I dropped the phone twice getting out of the car and once when I slipped and ejected everything in my hands skyward.
The case completely covers the iPhone with little doors over things you need to get to or nubs that allow you to push buttons through the rubbery outside. It means an extra step to take a picture to uncover the camera lens… putting up with that in exchange to not have to buy another iPhone when the inevitable drop happens.
I thought I would pass on a link that I just received in an email for 20% off the case. It isn’t a cheap case, but this is a great example of you get what you pay for (they offer other colors than the black I chose too).
