Just like our mother used to say: "backing up your data isn't just a good idea, it's the law!" (Or something like that.) Anyways, PC World has a nice little roundup of address book backup solutions for your phone. They run the gamut of convenient, but expensive, carrier-based solutions, interesting SIM card readers and hardware dongles, and tried and true PC software for those with USB sync cables, so hopefully you can find something that fits your style. We prefer to have our people call their people when it comes to using teh phonez, and don't know these "address books" of which we speak, but your mileage may vary with this method.
