How would one find such a thing? Or are you thinking of taking the back of a white Mini and installing it to a black Mini.
The cheaper way around this is to take the moshi screen protector and install the black one on a white Mini.
But I don't have a white Mini.
Not sure what the back cover goes for to replace but yes, your first statement in your reply to me is what I was thinking or doing or wondering if anyone was also at least thinking about it.
It may not even look that good to tell the truth. I really do like the back of the white Mini, but I hate the front so hence I bought the black since the front side obviously is what I'd be looking at all the time while using the Mini.
