Ok heres my problem. About 2 weeks ago i went to the Apple store because i got an iPhone 4 with probably the worst proximity sensor on the planet. Literally i hold it up to my face and dont move a muscle and the screen flashes on and off. Its literally caused me to add calls at 3 a.m and hang up on 50% of my calls. So i asked if i could swap it out and the guy working said i should wait for the software update and getting a new phone would still have the same problem. So the problem is now my 30 days is up, and what if the update doesnt fix it? Do you think theyll still let me return it? ATT store wouldnt let me swap out either.......
