I don't think the phone is warped I think its was designed that way intentionally. Mine is the same and I believe it was an intentional design choice to make it more comfortable to hold.
I went go-karting a few weeks back and it bent my phone. I bent it back carefully... still not 100% flat but it's better than it was before.
