The iPhone 3G does a whole lot more than its predecessor, and that means that the battery is going to drain much faster. All of those cool new apps will also suck up the juice. The iPhone 3G Solar Charging Case will offer some protection for your iPhone 3G and also has a built-in solar panel that will collect the sun’s rays and turn them into electricity.

Power is stored in a 1,500mAh battery that will give your phone a full charge. Recharge time is about 3 hours. It may not be the most beautiful of iPhone cases, but it’s a good option for those who are thinking green with their gadgets. The price is $54, while the sun’s rays are free.

Popular iPod case manufacturer iSkin is introducing a new case accessory specifically designed for the new Apple iPhone 3G. It is called the iSkin revo2 and pricing is around $40.

The iSkin revo2 encases the iPhone 3G in a protective silicone material, according to iSkin. This is designed to protect your mobile from dings and dirt. Joining this layer of protection is antimicrobial product protection as well as a face shield which is transparent and detachable.

There are tons of ways to protect your iPhone. But hippies and Ewoks are going to want something different. That something is wood. Why not go all natural with your iPhone 3G? Miniot’s form-fitting iWood cases are all natural hardwoods like oak, cherry, mahogany, walnut and something called padouk.

One downside to adding natural beauty to your iPhone is the price tag. At $125 each, they’ll cost almost as much as the iPhone 3G itself. If the price is a bit steep for ya, you can always try your hand at whittling your own, but I shudder to think what the end product will look like.

Back when the original iPhone launched I was upset that a few short weeks after I got my phone it had scratches all over it. To keep this from getting any worse I got my hands on a product from Zagg called invisibleSHIELD. The stuff is made from a super strong and invisible film the military uses to protect the blades of helicopters from scratches and nicks.

Zagg cuts the stuff to the exact fit for the iPhone and has for the last three weeks been offering pre-order kits that protect the screen and body of the iPhone 3G. Zagg says that so far it has had 50,000 orders for the iPhone 3G kit.

A few days ago, we told you about some new iPhone cases on the way from Belkin. Well, regarding one of those cases, the guys over at Crave noticed something interesting. Something almost conspiratorial.

The case in question is Belkin’s new “Micro Grip” for the 3G iPhone. It’s basically a bunch of interconnected Zune logos. Conspiracy aside, I’m not sure this is the case to go with, since it’s more or less a rubber web and won’t offer complete protection. Plus, it’s got me paranoid now and I’m not sure where my allegiance should be. Apple or Microsoft. Or is this saying that it’s alright to be both? I’m confused. And probably being watched.

When Apple announced the iPhone 3G this week it was a given that cases and accessories would be deluging us in the next few weeks. One of the things that most iPhone 3G buyers cone July 11 will be looking to buy at the same time will be a case to protect their shiny new phone.

To that end Belkin has announced a complete line of nine cases specifically designed for the iPhone 3G. The cases are supposed to protect the iPhone 3G and add looks to the device at the same time. The Belkin line includes silicone cases, arm band cases and polycarbonate cases in multiple colors, patterns and styles.
