IPod 5 vs iPhone 4? Is it worth it?

I have had an iPod 5 for a while. I use it to listen to music on my way to school, and surf on the internet when I don't have a pc near me. I'm very happy with it. But I can't call with it. I have had an HTC Desire as my cell phone for over 2 years now. But now I need to buy a new phone. I really want an iPhone. (iPhone 4, iPhone 5 is out of my price range) So my question is: Is it worth paying around 500 dollars for an iPhone 4 when I already have an iPod 5?
