Today Pebble released update 1.2. So far, the only thing I have noticed is Gmail support. But that is huge. I know with Android you can already do this with various tools, but for non jailbroken iOS users, this is a great new function.
Now this is not the greatest thing in the world if you get LOTS of email. You may want to set up filters or something so junk or not so important emails go into folders. Or you may want to set up a new Gmail account and then create rules to only send important emails to this new account.
Anyway, update your apps. Its sweet.
