Just a little information, what warranty do you really ever have? In most cases, the idiots doing the warranty have no clue what a bootloader is, let alone if it's locked or not. As far as Metro goes, there is no warranty. If you buy device insurance, doesn't matter if rooted, but then again, you're paying pretty much full price for your deductible. Don't be a wuss, root your phone! Hey, did any of you check each other out? Kinda weird, most of us on this thread joined XDA back in the mid 2000's, I saw at least one of you had Nexus devices, as did I. The question is how did we end up with this crappy phone being members of this website 10+ years?
