Although I am NOT an apple fan-boy, and tend to stay away from apple gadgets, this tip may come in handy to all you iPhone / iPad / iPod users.
Here, I will help you retrieve the IMEI of a lost iPhone device. I used this technique recently to help one of my friends get the information for reporting in a lost iPhone.
Although I haven’t tested this for the iPad / iPod, it should (in all probability) be useful in getting the serial number for the same.
The need for the method arises if you lost a 2nd hand iDevice or you have misplaced your bill / original packing and need the phone IMEI to block your stolen iPhone (or report the loss to the local law enforcement / police and / or the network operator).
The only caveat here is that you should have used iTunes in the recent past (which as an iDevice owner, you must have!).
