Change the IMEI code on an iPhone with this simple guide. Find a clean, well-lighted surface free from dust. Place your guitar in a position where you can easily access the main body cavity, where the wiring you will fix is located. Depending on your model of guitar, this will either be under the pickguard, such as on a Fender Stratocaster, or behind a removable panel on the back of the guitar, such as on Les Paul models and their clones.
Type in "cd Desktop/ZiPhone" in the command prompt and press "Enter." Connect your iPhone to your computer.
Type "ziphone -u -i a123456789012345" in the command prompt. Change the numbers to the IMEI code you would like to change. Wait for the program to locate the zibri.dat file. Your iPhone will automatically reboot and your phone is now using a new IMEI.
