We over in the HTC forums have the same prob, unlock the bootloader then you lose all warranty on your phone. We have faulty WiFi antenna on the One X, the contacts don't connect the antenna correctly, HTC say that if you unlocked your bootloader you can't get the antenna fixed, no one can say how unlocking a bootloader and WiFi antenna can be connected in any way, but HTC are being dogs about it. As for the yellow tints, they are a common problem across the bord, it's only the glue sticking the screen and the glass, play some games, give your phone a good use to heat it up and you will find that,the yellow tints go after a week or so
It's odd to see that it seems all/most mobile manufactures some what lack customer service.
