How to track a iPhone 4 that is offline?

My iPhone has been missing for a week and I'm now thinking it has been stolen. It is offline and I was not smart enough to set up an ICloud account. Any idea son what I could do to track it?

Unfortunately, my friend, there's absolutely nothing you can do to track it if you don't have security/tracking software installed on it, and even less chance of tracking it if it's not online.
