I know a few of the major carriers offer this type of service for a monthly fee. I suppose you could look into that, however there's a build in flaw to this model. If you use a carrier's backup service for your address/contact list, you can only use that with phones from that particular service. For example, you could transfer information from one AT&T Wireless phone to another AT&T phone, but you wouldn't be able to move data from a AT&T phone to a Nextel phone. I've seen some third-party devices out there that will help you move contacts from one service to another, but I haven't seen backup service that will allows for this functionality without manual (hardware or PC software) intervention.
