FYI, Just checked by loading Zaploc on my N900 and it seems to check into facebook fine, so it's not a protocol issue. I'm betting it's a permissions issue on individual facebook accounts.

Also, good to know that the connection data for each service is in the .zaploc folder. Worst case if I can't connect to a service, deauthenticating and removing the files there should reset everything for that service, yes? Always good to know how to do that, since sometimes services change how things work under the hood and re-auth is needed to make it go.

I had problems with the N900 service updating pictures until I did this with that connection on FB and on the device. (And that was much harder, involving teh gconftool to remove entries. )
