I have my iPhone 5 since day one here in Germany. The sleep/wake button started acting up just a week ago and I remembered reading something about the issue. Only two or three weeks ago I planned on having the battery replaced but then I came across this thread and read about all the nice things Apple would do to my almost two year old phone.
I called it in on a freaking sunday(!) 4 pm, right after I got home after a heavy party weekend. What else would you do!?

So UPS picked up my iPhone the next day / monday at 12:30 pm and I got it back half an hour ago 10:20 am (CET) thursday.

It's the same / my beloved phone. They changed the flex cable, battery and camera.
This is not the first time that I'm really really happy and impressed with their service.
