Yeah, I wasn't real happy when I lost access to the .tmo.blackberry mail from the pc. Then started receiving spam to that address.....Then I deleted .tmo.blackberry mail from my BB altogether. That's the only restriction from the old BWC that I can think of.
I used to have a lot of fun with it, changing my "sent from" email address. Loved telling co-workers ( from [email protected]) that they were fired. I loved being able to keep my emails even after deleting them off of my BB
