iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
Next iPhone: Double Resolution Display, Front Camera, Multi-Tasking?
- A4-family CPU system-on-a-chip
- 960x640 double-resolution display
- second front facing camera
- 3rd party multitasking in iPhone 4
The front camera and multitasking have both been suggested before. There has been overwhelming evidence that Apple has been working on video chat for the iPhone OS. Meanwhile, multitasking was believed to have been originally planned for iPhone 3.x but later scrapped. The double-resolution display is completely new information, though would make sense given the increasingly high resolution screens of the competition.
Update: Engadget reports that it is hearing that the next-generation iPhone may be called "iPhone HD" and be released on June 22nd.
