You have to go to field test mode by entering *3001#12345#* and go to Versions, there you will see an LCD Panel ID. I don't know who makes the two LCD panels, but one starts with a 7 and one with a 5. Mine is, 7455232. List yours and vote on which you have. I had a version 5 panel and found it to be way more crisp and even before I had to exchange out my iPhone.
