In May I was getting a new IP5 on Applecare and the other person waiting has his 5S. His complaint was his phone was curving from sitting in his pocket. I asked the Genius @ it-lott of 5 & 5S have this issue.
Before you know it they'll be calling this issue "Bend-gate." LOL! I, too, watched several videos today where people were testing the bending properties of the iPhone 6 Plus. It seems that there is a weak point in the aluminum body at the bottom edge of the - volume button. In reality, though... it's 'aluminum...' it's going to bend.
I should also add... all reports and video tests I've seen have made mention that this truly depends on how tight your pants are. So, an iPhone 6 Plus + skinny jeans... I'd say it's a no go. But really... why would you want to wear skinny jeans anyway??? LOL!
I agree I'm waiting on a Otterbox defender case I usually use the clip on the case holder and clip it to my front pocket or belt. I wonder if it does bend does it effect the metal on the iPhone where the glass connects to it at all or if the glass flexible too
