Hi. The Twitter application on facebook doesn't work with facebook- pages.
Example: I am in a band. We have a "Page" on facebook. We also have our own twitter. These aren't syncable with the current facebook- application. It CAN be installed to the facebook-page but you cannot link it to the proper twitter-account. This is probably because a "page" does not have it's own facebook-account. -Thats just a guess though. Just wanted to report this. Maybe it's worth looking in to? (Facebook-twitter works like a charm with normal facebook-profiles. Just not with pages) Fenx for everything u guys are doing! :) /Rob
