So word on the street is that Apple could be using sapphire for the iPhone 6’s display. This has reportedly been “confirmed” by an expert who believes that the rumors have credibility, however according to a recent report, it seems that apparently there have been some production issues regarding sapphire which means that supply will be somewhat limited at the start. What does this mean? Could it mean even more delays to the iPhone 6? Well maybe not, because according to the rumors, Apple could instead use that limited supply of sapphire for the 128GB 5.5-inch iPhone 6, so if you’re willing to pay more for the larger iPhone and pay even more for a larger capacity, chances are you will most likely end up getting a regular glass display instead.
