How to sync my Iphone 5 to my Itunes?

I have a PC and just got the Iphone 5 today. I can't seem to sync my phone to the Itunes. The devices tab that is supposed to pop up in the left hand side of my Itunes is not showing up. Can anyone help me out!

Try opening iTunes first, then plug in your iPhone. It should recognize it and start to sync

IPhone 5 requires that you update your iTunes to iTunes 11 If you haven't already done so.

Try rebooting with the iPhone connected. That's what I do when my iPod doesn't show up in iTunes.
