I have had two pixels die on my iPhone since Friday launch. I have taken very good care of my phone and have never dropped it. I thought that it was probably a fluke but I went online to see what was up. I've read multiple posts in other forums (sorry, can't remember the names but a google search should find them) describing the exact same problem I'm having. Although I really like the iPhone I will be returning it and keeping my tmobile service until rev 2 comes along. I hope this information is helpful to others.
