IMEI stands for International Mobile Equipment Identity.Note that this ability is similar to the assisted GPS feature of the i Phone 3G and i Phone 3GS, with the difference in that turning ON Location Services lets i Phone and its applications use this tracking info immediately (less than 10 seconds).Turning it OFF means this tracking info from the cell towers is simply not processed on the i Phone, but is available if needed.These numbers (or codes) work on most GSM capable phones, and the i Phone is no exception.You must tap dial after each number (unless specified differently in the description).
