Uhhhh, not to rain on your parade but the device I've been using for the last 6½ years - a Motorola Defy - is waterproof (IP67) yet still has one of those 'crappy "back cover[s]" which "pops" open' (with a latch to prevent it from popping when popping is unwarranted). It is also supposed to be rugged and I guess this is confirmed by the fact that it still lives after those 6½ years in my care. Need I say I have a farm with quite a bit of forest, the which I regularly maintain using tractor, saw and axe? That phone has survived nevertheless. When it gets too disgusting to hold I clean it under running water. Just a week ago I happened to use the thing to provide some light when changing light bulbs in my wife's car. What do you know, it slipped down and landed on the plastic cover underneath the engine, there was no way to reach it without disassembling part of that cover. Since we were on our way home I just left it there, drove home (about 11 kilometres) and got out the tools required to rescue the phone. I found it wedged between the oil pan and the plastic cover. It was no worse for the wear other than possibly some extra scratches on that 'crappy "back cover"', I wouldn't know since the thing is scratched beyond recognition anyway. Yet... it still works. I guess I don't need to elaborate on the survival chances of an iPhone - any iPhone - in these circumstances.
