BIS 3.0 Two-way sync

Over the weekend we had tons of reports that two-way Gmail sync on BIS was finally alive and kicking. The feature should allow for synching of both read/unread messages, as well showing sent messages on your device that were composed in the Gmail web app. While it doesn't seem to be working for everyone (myself included), it looks like a ton of users are up and running. I did manage to get my sent messages to sync up, however anything beyond that is a no go on my end. So we want to know if its working for you. Leave a comment and let us know (yay or nay) and be sure to include your device/carrier information as well. We'll keep you updated as we find out more. Thanks to everyone that sent this in!
