Looking to buy a used RAZR MAXX via Craigslist (I know, this can be really stupid), but there are some really good deals now that lots of people are dumping Verizon. I will want to meet at a Verizon store and have it activated before I pay for it to play it safe. However, I can check the ESN now just to make sure that at least right now it's ok. My wife has a RAZR and for the life of me I can't figure out how to find the ESN. On my Droid X2, I just remove the battery and it's right there, easy to read. Since the RAZR doesn't have a replaceable battery, I guess the rear cover doesn't come off? So, where do I find the ESN?
