Here's a cool tool that I stumbled upon. It's called ZYB (quite uninformative name, but typical web 2.0 lingo I guess). It's a free backup service for your mobile phone. Quite impressive what you can do on that site -- back up contacts, etc. and actually it's a bit strange that they even can get the backup to work over the mobile's GPRS connection. I've used it for a month now and I'm impressed that it's even possible to make a backup of your mobile that way. I don't know how they do it or why it hasn't been done before!
