Just wanted to share my story. So far I've had terrible awful luck with iPhone 4 replacements (Launch day speaker broke) Went through 2 yellow tinted screens until I find a nice one which the glass became loose. Had 2 more yellow tinted screens when I phoned up Applecare and they shipped me a brand new one in retail box. The brand new one was lightyears better than the replacements with a nice white screen. Then I pressed the home button in and it never came back up. Had to replace with another yellow tint. Phoned up Applecare and my senior advisor (If anyone wants him email/name) I HIGHLY suggest him and he did say I could reference him. He set up another brand new replacement. Received this one on Wednesday and the wake/sleep button is smashed in. You cannot press it. Applecare is shipping me another brand new one. Applecare said the yellow tint is a huge issue they all know of and replace on the spot now. But wow by far the greatest customer service by far I have ever encountered. Which is why I will always stick with Apple.
