That's really great that you had that experience. I'm going to try myself this weekend. I've gotten so so so many different varied responses from coworkers and freinds - some say they just replaced it for them, some say $149, some say $269, some say $379. That's a big big chunk of $$ to be sure.
Also disapointed is that after chatting with Apple online they only quote $269, and I'm very weary about taking the phone to the apple store because I called all three in the orange county CA area and got 3 different responses (mind you I got these phone numbers from apple.com they are the right locations):
South Coast Plaza: $269 and we send it off, it takes about 3 weeks (this was the oddest response)
Irvine Spectrum: We don't repair those, no, you'll have to try one of the other apple stores.
Fashion Island: It can start as low as $269 and go up to $650 depending on what's wrong with it.
I'm most disapointed in the fact that out of 4 iphones I've bought, all from AT&T stores, I've never once, in all that time, ever been offered AppleCare+ which I only learned about after i dropped my 5S a few weeks ago and did research about it. I've never even been offered AT&T's own insurance. I pay for just about every bolt-on AT&T offers, roadside assistance, etc. and have the max data plan I can get (5gb+tethering) and there are 5 phones on my family plan. I bring them a pretty penny every month, and AT&T's only answer is "there's nothing we can do for you" absolutely nothing. point blank period.
Then there's every single tech site on the interwebs saying that SOME apple stores (but never saying which ones) are offering iPhone 5S screen replacement for $149 and there's this big machine that does it in a vacuum etc. None of the apple stores would comment and non would confirm $149.
