I have over 100 FB Notifications that I cannot delete some are messages some are just X has commented on a picture.
I have deleted the messages on FB to see if that would allow me to deleted off the phone but no.
It appears that these are double notification errors. Basically I will get a notification twice if my blackberry freezes (app error ?523) and its these notifications that I cant delete.
If I need to delete the FB app how can I do that!

Options>Applications>Scroll the the FB app and click on the bb button and select delete.
or
Open up app world and then click on My World, scroll down to the FB app and delete.
