iPhone 3G Juice Pack? TestFreaks is out to make sure you have an accurate answer to that, and judging by their report after two solid weeks of usage, the response is an emphatic "yes." Not only was the device sleek enough to not be incredibly cumbersome, but it actually performed as advertised. Reviewers were able to get their iPhone 3G from near-death to fully charged (twice!) on a single mophie charge, leading them to conclude that it "basically doubles the run time of the iPhone 3G" in a worse case scenario. Granted, even they couldn't overlook the particularly large price tag, but if you've been running bone dry with any level of frequency, we suspect the asking price won't matter nearly as much.
