Back Up Your Windows Mobile Phone For Free With PIM Backup

This program is not only good for backup. Personally, I used it to get all my data from my old QTEK 9100 (WM5) to my new HTC TyTn II device.
Worked perfectly!!!

clipped from gizmodo.com Backing up your phone may not be as important as backing up your computer, but one day will come when you leave your cell in a cab and you'll be really happy you've got all your info somewhere else for safekeeping. PIM Backup for Windows Mobile keeps a backup of your contacts, call logs, messages, tasks, and calendar appointments for easy restoration on a new phone. It's even useful for when you need to wipe you old phone because of corruption or having to let your wife borrow it for the weekend after she lost hers. [PIM Backup via Eten Blog via Lifehacker]
