If you have an older iPhone, including the iPhone 3G, 3GS, 4GSM, or 4S, just pop open the SIM tray and you'll see your phone's serial number etched into the back of the tray.

For Newer iPhones

For iPhones after the 4S, the serial number is no longer etched separately on the SIM tray. Not to worry, though, you'll see the IMEI number engraved on the back of the tray, and Apple accepts this number as well, so you're good to go!
