The Icon Battery Pack for iPhone matches the uber-sophistication of Apple and delivers the extra punch with its visible “battery power” status. It uses EL lighting technology (supposedly the first to do so in the world!) for indicating the power status on its display and looks really swank! Features include additional talk time of up to 3 hours, or audio playback up to 18 hours. The company states that it is compatible with 3G and 3GS, I reckon a 4G version should be soon on the cards. One of those goodies that you can actually buy!
