Big Google user and interested in getting a better Gmail experience on the iPhone? You can use IMAP or set up Gmail as Exchange via GoogleSync in the Mail app to cover the basics, but you won't get stars and labels. You can use Gmail.com to get stars and labels, but you won't get iPhone Contacts integration, attachment viewing, or easy access to multiple accounts. For that you have to get a little more... creative. We'll show you how after the break.
