Solar Powered iPhone Battery

If you can still see the sun where you live, you could be charging your iPhone with its power thanks to the Eton Mobius ($TBA). This battery pack/case/solar charger is custom cut to fit your iPhone 4, and features a battery large enough to double your iPhone's runtime, a rear-mounted monocrystal solar panel, open access to all ports and controls, and a jeans-friendly form factor that won't necessitate bringing a bag along with you.
