If you choose IMAP, you can choose wireless synchronization where if you delete a message off your blackberry, it will delete it in your Gmail inbox. The downside for IMAP is that when you send an email or reply from your BB, it will not appear in your Gmail's sent folder.
If you choose POP, sent messages from your BB will appear in Gmail's sent folder, but no wireless synchronization however.
I use POP by the way.
