but what if there was a battery pack that could easily plug into the bottom of the iphone (that possibly doubled as a case). but the battery pack is just a slot to put a battery or two in so that there is always a way to keep a charge on an iphone especially on very long trips (ie: plane flights) that does not have a place avaliable for a charge. then when the battery is low it can easily be changed out.
just a idea...
