Unified inbox for gmail?

[uncbutterfly]

Maybe I'm being a complete idiot, but I've been driving myself crazy the past few days trying to figure out how to get all my emails (I only use gmail) to show in one unified inbox. My husband has a samsung continuum and he can see all of his emails from different accounts in one list. Is there an option that I'm missing to turn this on for the S3?

Any help would be greatly appreciated!

Thanks! I think I like the way the gmail app looks better than the regular mail app, but I could get used to this. I guess unified inbox was the one good thing I had on my old blackberry, lol.
