Apple will never give the customer a screen option (90% would be clueless anyway), or a battery option. Remember, Apple knows best! 

It will either be standard on all iPhones, or not at all.
Not sure why people give rumours like this any attention.
What has Apple done in the last 15 years, to make you think that this is something they might even consider doing?
It's such a bad idea.
if theres an option to have a sapphire screen there should be an option to have a larger battery.
Macrumors forums are most likely more informed than ABC's GMA.
Really? I am not. The only thing I watched is NY1 when I still lived in NYC.
Just seen on GMA that the sapphire screen will be an option for $100. Is it worth it?
