I really don't understand this. There have been reports of nearly every large smartphone ("phablets" apparently they're being called) built in the last 3 years bending or cracking under normal use, but two reports of an iPhone 6 bending, plus one guy monkey-wrenching it on camera, is cause for global alarm?
I just chalk it up to the annual "what flaw can we find in Apple's new device this year" brigade. 99.9999% of users will never have a problem, and in a month it will be old news. Don't sit on it or stick it sideways in a pair of skinny jeans and it won't be a problem.
