I dont know why but i think you can just buy an iphone off amazon.com or overstock.com and put in your own phone company sim card into it. (EX: like I could put my T-Mobile SIM card into the iPhone.)

If your iphone 3GS GPS locator is on, or if you have a app that helps you locate your phone on it for example 'find my iphone' you can use that app on another phone. If you do not you can contact your phone company or place where the iphone was purchased and ask themif they can track it down.
