I have a 7250 running 4.0.x and I was wondering if I would have to updgrade my OS before upgrading to the new BIS.
No, you don't have to upgrade your OS. I just switched to the new BIS with my 7250 and it works fine. When you respond to an email, it now uses that address as the return address and you can set up different signatures for each email address that you have linked to your blackberry.
