Where is, in the hardware, the IMEI/ESN located?
I have recently bought a Sprint iPhone 5. I want to use it on T-Mobile but as Sprint iPhone 5 unlocking service is not yet available, I wonder if someone knows where in the hardware the IMEI/ESN is located. With that way, I could change that hardware and change it to an AT&T one or is it a big issue?
Thank you in advance for all your answers.
