There’s a theory in the scientific community that if the world is ever wiped out by nuclear holocaust, the cockroaches alone will survive to repopulate the planet. I’m all for this, because a planet of walking, sentient cockroaches sounds crazy cool, and because if humans ever do destroy our ability to survive, then the cockroaches deserve their chance in the driver’s seat.

What the scientists are missing, though, is that there’s another creature with an even stronger ability to adapt and survive. Change its habitat, change its food supply, smash it with a hammer…doesn’t matter. It’ll survive. It’ll continue to grow and populate, and it’ll always do its best to match your purse. I’m talking, of course, about the iPhone case. Here are some for the new iPhone 3G. No need to be creeped out by them, but best to keep a can of Raid handy.

At the WWDC Keynote, Steve Jobs drew heavy applause when he announced the iPhone 3G headphone jack will be flush, not recessed as on the current iPhone. As I stated in our coverage, the response clearly illustrated just how passionate iPhone users can be, and how boneheaded Apple’s design team can be. But, surely no one will upgrade to the iPhone 3G just to get a flush headphone jack, right? Right?! Of course, not. At least, not as long as we’re also still dealing with Apple’s external microphone being placed on those horrid earbud headphones.

Thankfully, Griffin and JAVOedge are here with their Headphone Adapter for iPhone and Handsfree Stereo Headset Adapter, respectively. This is good because, considering the new iPhone purchase policy, it may be quite some time before I’ll own an iPhone that allows me to use my headphones of choice.

Reviews after the break.
