Due for release mid-August, MobileFun’s Solar Powered case contains a 1500 mAh battery that soaks up rays to charge your iPhone 3G. It’ll take three hours of fun in the sun to charge your handset with enough juice to function, and 10 hours to get a full charge. Pricing has not been announced.
And even if the saving energy isn’t your concern, this might be a good solution if you have issues with iPhone 3G’s meager battery life. Just make sure to slap on some sunblock.
