No - I personally think you're nuts because you think ALL iPhone 5's are crap based on your VERY limited experience.
You could've returned 100 iPhone 5s for problems and it still wouldn't amount to anything statistically relevant.
For what it's worth, I returned my first iP5 because of dead pixels. The second has been flawless (save for the nick I accidently put there when I dropped it - my iP4S probably would've shattered).
I also exchanged an iPhone 4S for an overactive processor issue that caused it to run very hot and the battery to die quickly.
I also had my iPhone 4's dock connector crap out on me (after over a year of use).
Point being, these are mass produced products and there will be hundreds, maybe thousands with defects - while millions are produced with no issue. This isn't an Apple-specific problem.....its the nature of anything mass produced by machines (which is just about everything these days). I agree we should hold Apple to a somewhat higher standard than other companies, but truth be told, there have been "issues" with iPhones since the beginning - and pretty much every consumer electronic in every category....
And by the way - I'm 100% certain if you went to Craigslist and tried to trade an iPhone 5 for an iPhone 4S - you'd probably have multiple takers. So instead of b****ing and moaning on an internet forum, do something about it....

Why the hell did you ever buy the phone in the first place?
I absolutely dreaded people like you when I worked in retail.....people looking to make a stink because they like to make a stink. I've got news....your 5 returns aren't even a drop in the ocean....and the iP5 form factor is phenomenal.
As I said above - no one is stopping you from going back to the 4S....sell the 5 or trade it. Easy and done. Seems you're just a glutton for punishment.
