The USB PhoneBook Flash Drive is a small USB device that can easily backup your cell phone’s contact info. Simply plug the drive onto your phone, click the button, and…. poof! Later, you can copy or modify the data on your PC (only Windows ME/XP/98SE/2000 are supported though) or upload it again back to your handset with another one-touch button. It supports various Nokia, Samsung, and Sony Ericsson phone models. Just check the product page (link below) for the complete compatiblity list. Oh, and the price is just $20.
