If you are an iPhone 3G/3GS owner who has just updated to the new iOS 4.2.1 platform, you may have been disappointed to see that the free Find My iPhone feature is not available on your model – by default, that is. Apple has always been known to push the sale of its newer handsets by making certain attractive features unavailable on the older models. This time however, they have simply chosen to make it a much more cumbersome process.
So technically, it is possible to set up the Find My iPhone feature on your phone provided the service is available in your country. This is how you will do it.
II : If you don’t have a MobileMe account yet, launch the application and create a new MobileMe account.

VII : Go to Settings > Mail, Contacts, Calendars > Add a MobileMe account and enter your MobileMe login credentials
VIII : Launch the downloaded application and enter the MobileMe login account to set up the functionality
IX : If the newer iPhone/iPad model is not yours, disable the MobileMe account from Settings and delete the application.
You are done. You can now track your iPhone or iPod Touch anytime it gets lost.
