The question of protection for your iPhone is one that comes up all the time. What’s the best case? What’s the strongest case out there? In reality, it really comes down to what YOU like and your tastes. However, if you’re looking for one of the strongest cases out there to protect your iPhone 3GS, don’t forget to keep OtterBox in mind.

We’ve reviewed cases from OtterBox many times in the past. We’ve seen so far…

What’s Changed for the iPhone 3GS?

Today we’re going to take a look at the iPhone 3GS Defender case and what’s changed. In a nutshell, not much has changed since the form factor of the iPhone 3GS has stayed the same as the iPhone 3G.

However, the engineers at OtterBox noticed that OS 3.0 firmware brought some different acoustic changes. They increased the density of the foam donut found around the two bottom speakers inside the case to ensure superior sound quality.

Still One of the Strongest Cases Out There

Aside from the above change, the OtterBox Defender case for the iPhone 3G/3GS still offers three layers of protection: a clear membrane over the touch screen, a hard polycarbonate skeleton, and a tight fitting silicone skin on the outside. This all fits together perfectly in the included ClipStand holster.

The OtterBox Defender case weighs 54 grams and its dimensions are 4.87″ x 2.77″ x .8″. It’s one of the strongest iPhone cases out there without question. It does add some bulk and hide the sexiness of the iPhone’s design, but it’s a small price to pay if you work and play in extreme environments.

Special Note for invisibleSHIELD Users

Also, once again if you have the invisibleSHIELD full body installed, the Defender case will fit if you squeeze the iPhone in tightly, but your invisibleSHIELD application will be damaged. So be warned! Check out the pictures below (and click here for more pictures)

You can’t go wrong with an OtterBox if you’re looking for the strongest protection out there for you iPhone. At the price of $49.95US, the OtterBox Defender case is on the high end of iPhone cases. But like I said, if you’re a clumsy fool (that is also willing to invest in a premium case) and you always drop your phone, this is the case for you.
