Some of us are phone-case people and some of us aren't. Those in the latter group who preordered the iPhone X may want to consider some kind of protection for their new smartphone, though, because the iPhone X will be quite expensive to repair. According to Apple's service pricing support page, it will cost $279 to repair the iPhone X's screen for customers who don't have AppleCare+, the company's extended warranty. All other damages to the iPhone X that need repairing will cost a whopping $549, over half the price of the new phone's base model.
