I agree that an IMEI, in theory, never changes.

We should also think about what a "device instance" it is. I used it  
on purpose in my previous e-mail and you immediately jumped on board.  
Wasn't a device instance the "general representation" of a device  
model? Let's say the "Sony Ericsson W810i", but my own W810i is  
actually a specific instance of that generic device instance. All  
W810i will have a TAC number in common, but mine has one that nobody  
else has. I have Opera Mini installed and when I use it I create a  
combination of device hardware+software that is different from many  
others and might be equal to some others.

So what is a "device instance"?
