I beleive this was some has happened with the new BIS 2.6.
I was looking at my view folders today, and I noticed the "inbox" per email account, and I also noticed I have a Spam folder inside the inbox.. I did not have that prior to BIS 2.6, and to my knowledge there is no way to hide them.
8830 -> 8330 -> 9550 -> 9650
Just think about how far BlackBerries have come from then till now... And what else is coming.
