I was having issues with proximity sensor so I made an appointment at the Apple Store. Went in on time and was greeted by Genius. He said his wife had the same problem and that it was going to be addressed by os update but that he would replace mine with a new phone anyway. Whole thing handled in less than 5 minutes. This is not my first experience with a problem with an Apple product and this is pretty much the way that it's been handle for me everytime. I will most certainly remain a loyal customer because of the way I have been treated. After seeing so many negative experiences here I thought we could use something to balance it out with.
