If you weren’t aware, Microsoft recently released a Facebook application for Windows Mobile. We’ve heard some users have been having problems with installation and a new copy of the app has been posted. This version should help anyone that was getting the “cannot install due to insufficient privileges” error and it should also help with some hanging errors.
You’ll want to uninstall the old application and then make sure that the facebook.vol and fbmail.vol files are deleted from your root directory before reinstalling. You can get the new .cab file at the download center or from your phone.
