On Christmas I received an iPhone 5 as a gift. Today, however, I noticed a small, barely noticeable, fracture in the bottom left on the bezel (seen below.) Earlier this morning I was shoveling snow and had it in my upper jacket pocket. I came back inside and checked to see if I had any new messages, then placed it back into the pocket. About an hour later I was cleaning the front glass when I noticed the crack. I never bumped into anything and had never dropped it before then. I am thinking that there was a manufacturing defect in the glass, then after being exposed to the mildly cold (just above freezing) then back to room temperature caused it to fracture. It is still under warranty and was wondering if that would be covered.
