If you're carrying a Windows Mobile device, you should probably be using Dashwire. It's a great program that allows two-way syncing of your phone's info with their web client, and best of all its completely free. Users can back up not only standards like contacts, email and pictures, but nearly everything on their phone
from text messages to call logs to ringtones. It offers a Visual Voicemail service, and backs up most of your phone's settings. Users can even carry on SMS conversations, which run through the phone, via the web client. They can also have the device sync in real time or opt for manual syncs. It works on any Windows Mobile device -no matter if its 5, 6, 6.1, Standard or Professional-and since it's a web-based client, it works independently of your computer OS. In the near future, they plan to support S60 devices as well. We've been loving it since the beta, so head over and download their newly-released 2.0 client today.
