gmail wont setup on iphone 5

Hello everyone. I hope most of you got gmail setup on your iphone 5 because I can't get mine to work. Ijust upgraded from iphone 4. I had gmail setup on it and it worked as of noon sept 21 2012. I then activated my iphone 5 and went thru the process of setting it to my style. Now I have been having a difficult time setting up gmail. iCloud mail works fine but my gmail isn't. I have tried imap setting, pop, fetch off etc...

also my google authenticator seems not to be compatible with ios6 at least it's my impression. Someone or all of you help me with this.
