Well, I just wanted to bring this topic because of my proximity sensor problem. I could not get the genius to exchange the phone because they were coming out with a software patch on 4.1. With this in mind I call apple care and they told meto send my phone back and then they will fix it and I will get a working phone, the only issue is/was I was going to be without a phone for 3-5 business days. I called a friend of mine who worked at apple and I asked him about the issue I had with the phone and that I was trying to get a replacement. After a long chat, he told me head over to the mall, where he will meet me since he was working with a client near there. To make a long atory short, he plugged in my phone to his computer, he then told me to go to a genius and to tell him my phone keeps freezing when closing apps. I asked him why? He said "i got apple's diagnostic soft program" and is telling me that your phone frozed 13 times since you bought it. With that excuse I hit the apple store, the genius told me that it shows that I requested an exchange because the proximity sensor before. He had a little of an attitude, but i told him how back the phone kept freezing.....it only took 5 mins and I was on my way with a refurbish phone that looks new. So far so good. Question, is this software anywhere available? My buddy will not even discuss thia with me, he said is private, any takers?
