The iPhone 6 is widely expected to feature a sapphire glass display, but the protective material could only be offered with more expensive models that pack the most storage.
Apple’s sapphire supplier in Arizona, GT Advanced Technologies, might not be able to produce enough displays to meet initial demand when new iPhones come out this fall. While opinions are varied as to how many displays Apple will be able to make, it’s being reported that sapphire could very well only be available in the most expensive iPhone 6 models.
