I've been a BB user for about 4 years now, always on BIS. I could've sworn that the last time I looked (a few years ago), I was able to create additional email folders and file messages into those folders. Is that no longer an option (or was it ever)? It seems the only thing I can do with my messages now is to mark them Saved.
On a related note, I have my gmail configured on my device as an IMAP account... it would be nice to be able to apply labels and archive them off my device if i want to refer back to them at some point. Does anyone know of a good method of managing email on a device under BIS that facilitates good organization?
