You have to enable Find my iPhone on this phone. If you didn't turn on Find my iPhone on the iPhone and you can't use it, you can't enable Find my iPhone. However, if Find my iPhone is turned on, you can track the phone from another device with the Find my iPhone application or http://www.icloud.com from a PC or Mac
