Facebook Authentication on Blackberry

Hey all, I've been checking out the Facebook BB SDK, find it to be a little bit complicated and not being able to debug it for some reason doesn't really help my comprehension of it. The use I need of this is quite limited since I only wanna be able to post to FB as status update and besides that just require the permissions.

On the BB side all I want to do is get the authorization token and sent it over to be persisted, now, how can i log back on to FB using only that token ? because I don't wanna prompt the user again for his credentials each time he wants to do a FB update. I also found that the tokens have an expire date on them, is there a way to work around this, would appreciate if anyone who has worked with the S开发者_如何学编程DK would give me a hand on this. Thanks in advance.

Just add permission "offline_access" when u login, token return with expire=0.
