One of the huge problems with updating your phone as often as we do is having to fork out the cash for a new charger every time you change phones. The iGo ($30) alleviates the situation by using different, interchangeable tops for the phone end of the charger's plug. Buy a new phone? No problem. Just buy the new tip, swap out the old one, and you'll be slowly ruining your new cell's battery in no time.
