COME ON people...
Just because something CAN happen, doesn't mean it's an "issue". While I seriously doubt the veracity of the "loose front pocket" claims, I am sure that under extreme circumstances it could happen.
The reality is, for 99.9% of people, it WON'T.
There is no "problem". If there was, there would be thousands of reports of bending phones. There's not. Not even hundreds. Dozens? Maybe. But out of millions of phones, taking into account the probability of a lot being lies too, means it's in NO way "widespread" or an epidemic of even minor proportions.
If you bent your phone, I feel bad for you. You did it. Not Apple. You can cry, and feel bad about it, but just because something breaks doesn't mean it's automatically someone else's fault.
Take it to Apple, plead your case, and maybe they'll take pity on you for breaking your phone and help you out. They NEVER promised it would be indestructible, they also never promised how much stress it could take. I know it can handle a LOT, but there's always some idiot out there that's going to push the envelope anyway...
Then they blame Apple. It's not about common sense, it's about taking responsibility for your OWN damage. If you want a sturdier phone, there are plenty you could sit on all day. The 6 is not on the list. If you need a disclaimer to tell you that... well, I think that speaks for itself.
