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.

That's good knowledge to have in case you ever need to activate an SE'd phone. Thanks for sharing mate!

You're welcome.

For Identifiable purposes of the device, just remember to leave the first 8 digits (Type Allocation Code) as Is.
