Well I though I had the perfect copy but tonight I discovered the accelerometer and gyro are off about 4 degrees. I tried the level in the compass app and its off. I also tried other apps that use the accelerometer and gyro to level the phone and they al show the same results. I rebooted the phone etc. My ipad and iPhone 5 are level. Some apps you can calibrate the level but its always off by default and there is no way to calibrate it globally. I assume the circuit board is slightly off relative to the case. I ordered a 5s from ATT online and it said it would be here mid october so I went to the store and they had it in stock so I picked it up. Turns out the one from att.com shipped and will be here tomorrow. I was going to send it back but I think I will set it up and see if it is better and return the lessor of the 2. Hopefully att will not give me a hard time. Funny thing is I got them both for $200 off using the early upgrade.
