I just noticed two dead pixels on my 4s. According to this article, Apple should replace it. My question is, will my Apple store have any in stock to replace with right now? Also, I have a Power Support crystal screen protector on the front and back. Will I just have to take a loss on this? I would be willing to by another set at the Apple Store and have them put it on if possible. Do they generally do a good job when applying screen protectors?
