Hey, I recently bought this phone on ebay, according to seller it has this dot (under the time/date on top) and no other issues. However, when the phone tilted I see those lines and the curve. The phone is still covered with apple of course, but will they replace it or fix it if i take there? The phone is currently unlocked so I want to use it until there's unlock for newest firmware and baseband (whenever that occurs,) but I just want to make sure apple would fix this for me if I take it. TIA Also, the watermark sign is white.
