Backing up your Mobile Phone data is real easy with "Bubble". Bubble is a subscriber based service that allows you to backup and restore all your mobile phone contacts over the air, like making a phone call. No cables, no cradles, no problem. So you can bubble your phone anywhere, anytime.
Bubble is more adavanced than a straight forward data back up and restore service. It allows you to do a fully automated synchronisation between your mobile phone and your “Bubble”. This means during a synchronisation your phone will automatically work out what information has changed since your last sync and sends only the new changes to your bubble. Meanwhile, your bubble automatically works out if you have made any changes via the web site and downloads these to your phone.
