Looks like a manufacturer's defect. I don't see how the heck that is possible. It looks like a perfect slice as if it was done with a razor. Good luck in trying to get a replacement, unfortunetly, sprints replacement policy on cosmetic defects isn't the same as software issues. Unless you flashed a corrupt rom and brought it to the sprint store (which would be wrong), they would give you another handset for free.
