Engadget just heard from the boys and girls at RIM that the company did, in fact, deploy the long-awaited two-way Gmail synchronization capability to North American BIS users this week. What does that mean, exactly? Well, it means that if you've got a BlackBerry on any North American carrier that isn't going through BES, Gmail should behave more like it should -- deleted items will disappear from your phone, emails read elsewhere will show up as read on the device, and you'll have access to all of your sent items.
