Yes.

Theoretically, I guess so.  However, keep in mind that this is really 
about dealing with odd specifics of how certain phones behave more than 
anything else.  Some phones won't subscribe but still expect MWI.  Some 
phones may freak out if they receive MWI when they haven't subscribed to it.

You are quite welcome.
