Hello. I'm gonna buy new iPhone 4 this week and I'm afraid that it's going to be yellow tinted. I have read few topics (http://forums.macrumors.com/showthread.php?t=1000042) about this problem and now I'm scared. One of the iPhone that I wanna buy has SN: JV138UMTDZZ, maybe that can tell you something about its screen. Maybe some factory has only yellow screens, or something like that?
