General Screen swap question

view story

http://androidforums.com – I am a idiot and didn't purchase insurance on my phone and I broke my lcd screen. I have a friend with a razr who had the insurance. My question is if I took the screen out of her phone then turned her phone into her insurance would there be any way for the insurance to find out what we did? Also are the lcd screens for the razr and the maxx the same? (General)
