iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
Apple Recalls iPhone 3G USB Power Adapter
According to Apple's support article on the recall, the adapter was included with every iPhone 3G sold in the US, Japan, Canada, Mexico, Colombia, Ecuador, El Salvador, Guatemala, Honduras, and Peru. The adapter was also available as a standalone accessory in those countries, as well as Argentina, Chile, Costa Rica, and Panama.
Users with ultracompact power adapters should immediately stop using them until they exchange them for a new, redesigned ultracompact adapter.
In the meantime, they should charge their iPhone 3G by connecting it to their computer with the USB cable that came with their iPhone or by using a standard-sized Apple USB Power Adapter (with fold up prongs) or with a third party adapter designed to work with the iPhone, such as a car charger.
Affected users may order a replacement adapter via Apple's web-based form or in person at an Apple retail store beginning October 10th.
