Downgrading iPhone 5 to iPhone 4

Can I use the same SIM card I now have, or must I order a new one? If I need to order a new SIM, can someone post a link or number I can contact? Much thanks. 🙂 [If it matters, I use ATT on an auto renew, pay as you go monthly plan]

The iPhone 5 has a nano sim, the iPhone 4 takes a micro sim. You either need a SIM card adapter or a new sim. Best to go to an ATT store for a new sim so they can set it up with your number. If you just order one online and activate it yourself, you will get a new number.
