Apple's yearly developer conference should see iOS 8, OS X 10.10, and likely some hardware.
Apple to Begin iPhone 5c In-Store Screen Replacements Next Week
Apple has begun conducting iPhone 5c screen replacements in a small number of stores in the United States over the past couple of months, but the January 20th rollout will represent a full-scale launch in all of Apple’s retail regions aside from Hong Kong and Canada.Broken displays that aren't covered under AppleCare+ will likely cost $149 per device to replace or repair, while displays that are covered under AppleCare+ are likely to cost $79 per device, similar to the pricing structure Apple employs for broken iPhone 5 displays.
In-store replacements/repairs for iPhone 5s displays are still in Apple's plans and are "coming soon", though are not expected to roll out next week alongside iPhone 5c replacements/repairs. The moves are part of Apple's larger shift to lower repair costs.
