a quick google search revealed that magpul makes one:
It's for the iPhone 3/3GS, not the iPhone 4.
I don't care what anyone says (not fussing opinions, just expressing my own) the otter box as proven itself to me over and over again, I'm a firefighter and it goes with me most places except for in the beast, so it has my regards as toughest out there
Both Otterbox and Ballistic make cases which offer a high degree of protection, the highest being Otterbox’s “Defender” series and Ballistic’s “HC” series. Both companies make cases for a variety of smart phones, including the iPhone4.
➢ Otterbox “Defender” series: these cases have 3 parts: a shell into which the phone is inserted, a cover which fits over the front of the phone, and a silicone outer case into which the covered phone is inserted. In addition there is a ratcheted holster into which the encased phone snaps. Although the phone can probably be used with just the inner case, the addition of the outer case helps hold the inner case together and adds substantially to the ability of the case to protect the phone. The iPhone 4 cases are available in black, red, and blue (very close to Dillon blue, which could be the deciding factor for some of us
).
➢ Ballistic “HC” series: like the Otterbox, this case has a shell into which the phone is inserted, a cover that fits over the front of the phone, and a silicone outer case into which the covered phone is inserted. It also has a ratcheted holster into which the encased phone is snapped. The iPhone 4 can definitely be used with just the inner case, but as with the Otterbox, the outer case adds to the structural integrity of the assembly and adds substantially to the ability of the case to protect the phone. Colors available for the iPhone 4 are black/black, black/grey, and black/Pepto Bismol pink.
➢ Otterbox “Defender” vs. Ballistic “HC”: Neither of these cases is small; for an iPhone 4, the measurements (to the nearest 1/16”) are:
o Naked iPhone 4: 4-1/2” H x 2-5/16” W x 3/8” thick (as measured by me);
o iPhone 4 in Otterbox “Defender” case: 4.85” x 2.67” x 0.66” (according to Otterbox);
o iPhone 4 in Ballistic “HC” inner case: 4-7/8” x 2-3/4” x 5/8” (as measured by me);
o iPhone 4 in Ballistic “HC” complete case: 5” x 2-7/8” x 3/4” (as measured by me).
For iPhone 4 users either would serve you well. Aesthetically, I think the Otterbox has a more “finished” look.
Ballistic has posted several videos on YouTube showing Ballistic-encased iPhones being dropped onto pavement from 25 feet, thrown against a wall, dragged behind a truck across a parking lot, etc. Those videos are pretty impressive and made my choice an easy one.
If you’re in the market for a tough case, I strongly recommend that you check these videos out.
Some people have noted a watermark or oiling effect between the clear cover of both the Ballistic case and the Otterbox case and the iPhone screen. I inserted my iPhone into the Ballistic case with the original protective plastic on the front and back of the iPhone intact (other than cutting away areas for the camera lens, etc.) and have noticed no watermark or oiling effect. And yes, the touch screen works just fine. I imagine this would work with the Otterbox as well.
Either case improves the feel of the phone and makes it much less slippery and less likely to slip out of a shirt pocket. Pricewise there is nothing to choose from as each case costs $49.99.
