Really do you have specific data to back that up. Like I said three times I do it all the time . Please let's stop generalizing folks unless you have specific engineering data that says exactly to the point x amount of pressure will bend the casing of a iPhone . I have yet to see anyone come up with hard data on this except you should not sit on one, well I do and I'm 230 lbs. so why after several iPhones I have not had one bend on me. I think the front pocket would be worse as the pivot of you is far more severe in angle than your back pocket.
Also who said and is there any written warnings from Apple saying anything on care of your product that relates to carrying a iPhone. There is none and this constant you should not have one in your back pocket is silly tell me where did you get that idea. Thin air , you and everyone else has zero proof that you are correct. Sure anything will bend at some point given the proper amount of pressure that's logical but not scientific fact that anyone has seen on this product. Now am I careful, sure I am just like carrying one which is usually the biggest percentage of damage to a iPhone is flying out of your hand. We all done it and it's not that hard to do. But even than do we have hard facts at a certain angle on a drop is sure death to a iPhone. No we do not or I never seen it.
I dropped one 4 weeks ago dead flat on its face as it cracked evenly across it besides watching it in horror hit the asphalt. Cracked screen alright but functioned perfectly. Seriously is it truly a bad idea carrying it in your pocket by scientific fact or by wife's tale opinion. Until I bend one sorry I'm not buying this don't sit on your iPhone. Now I do take precautions when on hard surface and other precautions but that's based on my logic not hard data. Anyway I'm done reading this BS no one has hard data here. People carry iPhones in there pockets and sure maybe some bend given a certain circumstance but there is no data on those circumstances. I'm not saying carry your phone in your pocket that's your choice but please stop this you should not carry it in your pocket, you have no facts to back that up. And worse make it sound like people that do are idiots well I'm not a idiot until I bend one from doing it. I'm a idiot for dropping one now there is no argument there. LOL
Not solely directed at you but unless we have real data than its a wife's tale. I agree anything can happen and it usually does and I also agree we should take precautions on care of these electronic devices. I have no argument there. We just can't say with utmost accuracy sitting on a iPhone causes damage. We simply do not have facts on that.
