What is the average cost of 5s screen replacement?

Since the ONLY place where you can get it replaced and still maintain your ability to have it serviced/supported by Apple, that would be $269 at the moment. They replace the entire phone. Screen replacement is not yet available for the 5s. It IS available in the US and some other countries for the 5 and 5c. There is reason to believe the 5s will be included in thaat program sometime in the future. Currently, the cost for screen replacement on a 5 or 5c is $149.

5S screens are not replaced at this time

Exchange price for a replacement iPhone 5S is $269 +tax in US assuming you do not have AppleCare +

Any word or rumors about when 5s screens will start becoming available? I've got a cracked 5s I've been living with in hopes that screen replacements are right around the corner (as they were for the 5c).

rumors and speculation are prohibite by the TOS.
