This update allows a lot more features that you’re familiar with on your desktop or laptop based Gmail. You can now see your outbox, and mobile draft mails. Also, you can view your contacts, and call them from your address book. If you’ve signed up for Google apps, and use your own domain, there is support for that too. You can also set up multiple accounts, again as you are able to do on your comptuer version.
It also seems to load up a little faster.
