iPhone 4 Mobile Charging Cases?

Has anyone come across a mobile charging case for the iP4 yet? I loved the Rocketfish Mobile case for my 3GS, made the battery last easily 2X longer, excellent for traveling. So far they do not have anything for the iP4 yet or any other company that had them for the 3G/3GS. I've looked just wondering if anyone knows of another product? Do not want any other type of mobile charging, just one that is also a case.

Bump, anyone?? Could really use a case like this.

Thanks for the smart ass comment but that product is NOT available until the end of September. Does me no good at this point. Obviously I know there are many in the works but I could use one, well, NOW.

These cases are not meant to charge the iPhone.. You're supposed to attach the case when both are fully charged keeping your iPhone at 100% for 2X as long. If you use it to charge the iPhone it will only charge it about 60-70%.
