i wasn't able to get the facebook app or berry weather to work.. i don't have a blackberry data plan, i just have medianet. i had an error with opera mini at first (it had worked in the past) but i had it run the network scan thing, and it then worked. i have TCP configured properly, and the blackberry browser works, gmail works, etc.
There is only one carrier/plan I know of that would allow Facebook to work without a data plan. Telus' Student Plan has no data (browser, email, app world, etc), but allows BBM, Facebook, and other RIM I'm apps (WLM, YM, etc).
Otherwise� no.
