What is a good service to use to backup the address book on my Blackberry 8800?

Question

I know how to back it up on my computer, but would like to do it online as well. My provider(ATT) has this service: http://mobilebackup.att.com/how_it_works.html

Unfortunately, my model phone will not work with this service, but this kind of service is exactly what I'm looking for.

Answer 1

You can install Yahoo GO! to your phone and sync your address book with your Yahoo account's online address book.

There is no charge for this service.
