So I've been hearing some not-so-good things about the lcd on the 16GB iphone.... how MANY of them contain the negative black effect. Actually, I think this is true for ALL new iphones, am I right? What's the deal here? If I was to purchase an iphone today, I wouldn't like my chances on getting a good screen. Anyone else feel like this? So what's the magical serial number here? I've heard week 4 and week 5 are good. They have the good panels I believe - 7459072 & 7586304. Any advice? Thanks.
