If you misplace your iPhone, Apple’s MobileMe service can help you find it. Log on to me.com to view a map that shows the approximate location of your iPhone. If it’s nearby, have it play an alert sound to help you find it, or display a message on the home screen to help someone return it to you. If displaying a message hasn’t resulted in its safe return, you can initiate a remote wipe and restore your iPhone to factory settings. Unlock iPhone 3G
