I wish I could get a good picture of it. I tried a few photos last knight but I can't get a good one. This might be because the camera I'm using kind of *****. I'll try but I'm not sure. The picture I referred to is just a photo I took of someone with the iphone in a poorly lit room so the shimmering shows up in about 1/3 of the photo. If you have the problem and want to try to get a good piece of evidence, I would try doing the same.
I was actually trying to get a photo so I could print it and send it with the phone for repair to help my chances of the repair person recognizing the problem, but, besides the poor quality camera, I don't really know how to get the lighting right to take a decent picture, but I'll try some more today and post it somehow if I get a good one.
As far as replacement of the phone, a warranty replacement is going to get you a refurbished unit. I suppose that you just got lucky by getting a new one. The two apple guys I have dealt with were really nice and even apologetic for my having had problems. I find that if you're trying to get warranty service and you encounter resistance the best strategy is to be demanding. I had to go on quite a rant once with dell, but it gets things done. If an employee is being rude or obnoxious you should keep in mind that you have the upper hand because there's a line they can't cross because of the threat of losing their job. So just one-up them and be rude back, and it helps to speak loudly so everyone can hear. Yeah, you might end up looking like a d-bag, but it's just in front of strangers and sometimes you have to do this to get what you deserve. I'm not saying insults or cursing is good idea, you just have to let them know that you're going to get what you are asking for. In any case they are obligated to honor the warranty, which includes manufacturing defects. Since apple has fessed up to this problem with the new ipods, it's really only a matter of enforcing your rights under the warranty agreement.
Asking to speak with a manager also helps. To me, the "when are you guys just going to be happy.." comment doesn't make sense anyway. Nobody with these issues is trying to get something undeserved; we just want a phone that is of the qualify that it should be. And it did cost $400...
I'm sending it out for repair today and I'll give an update concerning the outcome in a few days when it comes back.
