I haven't canceled my order yet, but I'm pretty sure I am going to. My phone lives in my front pocket. I don't wear anything close to skinny jeans, but I still don't want a bent up phone. I'm a bigger guy, so of course I'd never put a phone in my back pocket. Ever. But it stays in my front pocket while I'm at work - that's for nine hours (minus a one hour lunch and two 20 minute breaks). My iPhone 5 has lived in that pocket for two years now. I size checked a 6 Plus and it will indeed fit comfortably in that pocket, but I quite frankly don't trust it now.
I ordered a Space Gray 64 GB iPhone 6 Plus. It is scheduled to be here mid-October. But, since I'm porting my number to Verizon with this order, canceling it would be quite the hassle. I will probably just return the phone for a regular 6 once it arrives.
