Want to get my replacement phone but im rooted?

SO my phone is pretty banged up the phone case is about to fall apart, i got a crack on the screen and another crack on the rear camara, this is all do to me dropping it so much. It still working like a champ but i want to get it replaced. i got the insurance on my phone and i want to use it now because im scared that one more drop might just kill my phone finally. Will they say anything if i send it in when i get a replacement,will have to finish it off when the new one arives, or simply report it stolen and just throw it away. Its the htc evo by the way with cryogenmod installed
