Hey all, I'm the originator of the initial post.
I saw a question about whether or not they will be replacing other parts of the iPhone. From my understanding, yes and no.
Apple will only be replacing anything that is immediately available to them. The front display on a 5 is really simple as long as you have the full assembly with the small parts so it would take them less than 10 minutes and you're off. You also have to deal with the Apple store and appointments and all that.
Repairs like casings and stuff that isn't immediately available will not be replaced (at this time). So on a 3GS like someone mentioned, the power button isn't readily accessible so they probably won't replace it.
Things like backs for a 4/4S, batteries, cameras, those are all right there and quick.
We are also lowering our price from the $139 to compete with them. As someone mentioned, location will help. Unfortunately there are 2 Apple stores in close range of us, one of which is about 2 miles so we will be competing heavily. Don't want the hassle of going to the mall and getting an appointment and all that? We'll have you out in ~20 minutes. If that extra $30-50 is worth it to you to have them do it, feel free.
It's all preference. 🙂
