I just noticed today that, when I send an e-mail from my gmail inbox (on a web browser), it's now showing in my inbox on my blackberry. That never used to happen.
Same here. I figure it's part of the roll-in of the Gmail features promised with BIS 3.0. My account now has reconciliation of deleted emails both directions, though it's very slow from gmail to the phone. Read/unread status still doesn't reconcile from Gmail to the phone. As before, everything works quickly from the phone to Gmail.
