Can i have 2 devices on my itunes account?

So i have an itunes acount with my ipod on it but i just got an iphone. I changed it so i now have my iphone on my itunes account but i was wondering if i could have both on my account

You can. My brother and I have both of our iPods and my parents have their iPhones on the account as well.

Yes. And the applicable apps will sync to the opposite device.

I have 3 on mine and can share all the apps, books, music, etc between the 3.
