  1. Frowned upon is an understatement. Depending on the country you live in, it can be downright illegal. My suggestion is you not do it. Changing the IMEI can result in guys with business suits and handguns coming to visit. If you must change it you will need to contact Apple to do so.

  2. Changing or “flashing” an IMEI is a simple task if you work in R and D for the company who makes the device.

    They all have their own software tools and dongles for this procedure and if you’re in the industry it’s a daily “chore” as you normally have to erase the nand when upgrading the latest software and this loses a lot of the NVM (Non Volatile Memory)

    Anyhow, if it’s all “above board” why do you want to do this?

  3. It’s illegal to change it and on most phones would require actually opening the phone up and changing the chipset.
