You can use the Facebook Mobile application for Windows Mobile (free, written by Facebook themselves), written for the Tilt. Check
http://m.facebook.com from your phone, and all the way at the bottom should be a link to download Facebook Mobile for the Tilt.
Mine's now showing "Download a bookmark for..." some other phone. If you can't find the .cab, I'll attach it here. Just copy to your device and install. It's just like the iPhone app, allows easy photo uploading without emailing and everything.
The only caveat I have found with this app is that it will truncate status updates you post from it if they are too long.
