Sure enough Gmail is live in the app store. Unfortunately its not an entirely native application. Most of it is a native wrapper for a web view of the mobile site. We get push notifications(except that their broken right now), address book integration, and the ability to attach photos, but the interface is a bit laggy and still won’t format an html email to fit the screen.
I guess I shouldn’t be surprised. Google usually releases products publicly before they’re ready and then slowly improves them. Link to the app store below.
