Can police track an iphone without a sim card and that isnt connected to the network?

I use at&t & someone stole my old iphone 3gs that isnt connected to the network & has no sim card. It also was off when i lost it. Its not my main cell phone but i still want it just in case i break mine & need it for backup. Can they find it?

Did AT&T shut off your phone automatically or do you have the find my iPhone app it can also wipe off everything off your phone to and save it to iTunes
