I purchased my phone on release day and had the yellow screen issue. I have had many replacement phones during the first 3 weeks of release and all but one had issues. I kept one that was not near as bad, but it's not nearly as nice as my 3G was. Question is, are they still shipping/exchanging phones with the yellow/dingy/washed out screens? What about replacement screens ONLY from the Genius bar? Thanks for any info.
