I've been wondering about that too, as I'd like to upgrade to the iPhone 5 from my iPhone 4, but have been holding off until this set of issues has been resolved. I keep reading about everything from nicks, scratches, scuffs, dust under glass, dust in the camera lens, ... wow, the list goes on and on. I know it sounds petty considering how many much bigger issues we face in the world today, but I'm in the camp with those who aren't willing to accept "damaged goods" when I purchase a new high-end device.
So I continue to watch to see if these issues will persist with the iPhone 5 or if they'll be resolved. The one thing that I wonder about is this: there have been millions and millions of the devices sold. Some who post here say they've gone thru as many as 5 or 6 exchanges & they've all been bad - but the numbers here are minute compared to the millions of devices in the field. What about them? Are they all damaged too, and people just didn't post here, or maybe they just accepted the defects? or maybe it's actually a relatively small percentage of units that come thru with defects (and typical of online forums, its mostly those who have issues that post 😮)...
I'd really like to upgrade if I can get a good one - it seems like a nice upgrade from the "4". But there's still a 3-4 week wait anyway...
