If you haven't already read this thread read it. It explains more about your IMEI getting blacklisted, as well as changing it.

Also can you clarify if your going to refund the iPhone after receiving it. Or have no intention of buying it whatsoever and are going to exploit the warranty. Thanks!

I have no idea how to exploit the warranty. I was going to say empty box on arrival

In that case, the IMEI will almost definitely get blacklisted. I found this tutorial on how to change it: https://medium.com/@nothingsecure/how-to...45200ab3f6

Also read @mothered 's suggestion in the other thread:

Generally speaking, the IMEI number Is added to a pool of blacklisted numbers and when you attempt to connect the phone with a given carrier, they will see that It's blacklisted and decline It.

After doing a few Google searches, it seems that you can change your IMEI through some methods after jailbreaking the device. This should allow you to connect the phone to a carrier.

It can be changed, however the TAC (Type Allocation Code) which Is the first 8 digits of the IMEI number, Identifies the model & manufacturer of the device.

This means, If you spoof/change the IMEI number It will not be dedicated to the device and upon activation with a given carrier, It may well be rejected. That said, It will work with carriers who neglect to check the device It belongs to. As a safeguard, leave the first 8 digits, and change the remaining numbers. This way, the IMEI number will show up to It's corresponding device.
