I think cases have a lot to do with these bending issues. People don't realize sometimes how much force they're using when they're trying to pull it out of a tight case. I've seen some pretty tight fitting cases before where I have to literally struggle to take it off. I can see someone bending their iPhone while taking it out of the case and being like "Wow, it's even been in a hard case this entire time and it still somehow bent!"
I've been completely 100% case-less since I bought my iPhone 6 and it's not bent whatsoever. Sometimes it gets a little twisted, but I twist it back and it's all good, but that's not the same thing.
What worries me though is that the iPhone has been out for 2 months... these things have to last 2 years and I don't see that happening.
The thing that worries me here is that you say that sometimes it twists a bit and your response to it that you twist it back. Yes, that is great that you can do that but I would expect the phone not to twist in the first place. All this bendgate made cautious so I'm doing the waiting game to see. Either I'll wait for the 6S or I will just see in few months what the situation is then.
Shame, I was so excited to finally upgrade from my iPhone 4
