FTG Writes: Everyone who owns a cell phone knows the frustration of having their battery die in the middle of the day without being anywhere near an outlet. It has happened to us all at least once. Wouldn't it be nice to be able to avoid that every once and awhile? You could carry a rescue battery with you at all times, but many of those are either bulky or just not practical. Bracketron put out a product for the iPhone that puts both concerns at ease. The Stone Battery offers an easy solution in a small package for those always concerned about their battery life. Is Bracketron’s battery worth carrying around in your pocket or bag everyday though?
