Welcome to the group, cueva.
Someone else will have to help witht the verizon question. I don't know what enhanced versus extended coverage means.
It sounds like you will be using this blackberry on BIS and syncing to Lotus Notes using Desktop Manager. If that's the case, you will be able sync the PIM data but not email. New email is pushed to the blackberry by BIS; it does not sync inboxes.
See
