are there any of these protective cases + batteries that use or allow you to plug in the normal 30 or so pin iphone/ipod data cable on the bottom to sync and charge?
I've looked at this, Mophie, Boost Case, etc and they all seem to include their own USB/Micro USB cable. My car plugs into the 30 pin standard iphone/ipod connector and I'd prefer if it just charges w/ the same cable.
The extended battery life sounds awesome since I'm always on the go and on calls for work.
Not that I'm aware of. They all have the standard drawback, their own proprietary charger which means more revenue for them but another charger you have to pack (which is what keeps me from buying one).
