How much would it cost to fix a broken iPhone 6 screen?

That is the price for replacing the screen, not an out-of-warranty replacement. If they inspect the iPhone and there is no other damage they will repair the screen and AT&T will not be notified.

If there is further damage they will replace the entire phone for $299. AT&T will be notified.

For $109 they replace the screen. For $299 they replace the phone.

Yes, they'll replace the screen for that price even if it was accidental damage.

I dropped my iPhone 6 from 50cm, only 7 days from new and the entire screen shattered from the impact on the corner. The good news is the phone is still fully functional, other than the screen (which I can still read but the glass is so shattered that the plastic screen protector is basically holding all of the shards in place.

I called Apple in my Australian city and the guy told me that iPhone 6 screen can NOT be replaced and that I would need a new phone. I was like hang on, that can't be true so after Googling I have learned that many people are paying around $109 for a new screen which seams very reasonable.

The guy from Apple told me about this and I told him I was not offered it/ aware of it. Too bad now my phone is obviously damaged and not fit for Apple Care +.

I bought my phone from Myer (department store) and I was NOT offered any extended warranty, Apple Care or Apple Care +. I have purchased this for my Macbook and iPad previously but the lack of the retailer up-selling me, I honestly forgot that it existed and was just super eager to get my new device home.

I will call Amex tomorrow and see if they can cover any cost for repair/ replacement but I really will be extremely disappointed if after owning nearly every iPhone and having much bigger drops - and many of them - and no broken glass, it does seem the 6 is much more susceptible to breakage.

Here is hoping the genius will value my custom and replace my screen (or phone) at under $200 Aussie clams.

By then my Lifeproof case would have arrived too. lol

That is up to the Apple Genius who works on your phone. You won't know until you go there.
