You said the cover popped off, can you see if the battery itself is bloated/swollen? The cover should NEVER just "pop off." I have taken apart a RAZR, and the cover is on there pretty tightly, I had to use a screwdriver to pry it off (damaging the cover in the process, lol). If the structural integrity of the battery has been compromised, you need to take care of it, pronto, before it starts a fire. I would take it right to Verizon, they will probably be able to dispose of it safely, and of course they will have seen that it was defective and start the process of getting you a replacement phone. Turn it off in the meantime!! :icon_eek:
