Bring the phone to a TMO company store and ask. (They'll probably say no, because most cases of burn-in are user error - you keep the screen brightness up too high and keep the screen on a single picture too long. (The screen time-out should normally be set to about 30 seconds - if you set it to 30 minutes (and keep the brightness up), the screen is almost definitely going to burn in. [All screens eventually burn in, the only question is how long it's going to take - it it takes 5 years the way you run the phone, it doesn't matter. The same with your TV, it just takes longer, and the picture is almost never just a still picture.])
