Mobile Data Backup

I need a site/application that will back up a mobile phone's address book and other necessary data to a web site that the user can log into and edit. I like what [login to view URL] has, but I dont know what else is available. I prefer a project that is already completed so I dont have to wait long, but if I have no choice then I will have to wait to get it built. I would like the app to work on as many phones as possible (like funambol). Or this kind of app would be fine too [login to view URL] I like this because its a downloadable app that opens up wap pages. I have a lot of questions about this because I dont have a lot of experience with java, j2me, j2ee, etc so please be patient and answer a few questions that I may have so I can really understand what I am getting into. PM me with your demos, and ideas about this project please.
