iOS 9.3 is coming in the Spring and will introduce Night Shift as well as a number of other new features.
Keynote and Other iWork Apps Coming to iPhone? [Updated]
On a new feature page describing enhancements coming to its Mail application on iPhone 4, Apple has included a section highlighting how email attachments can be opened in third-party applications. As an example, Apple has included an image showing a presentation with a dialog box asking if the user would like to open the attachment in Keynote.
Keynote is Apple's presentation application originally developed for Mac OS X as part of the company's iWork suite. The company made a splash when it announced an iPad version of iWork, including Keynote, Pages, and Numbers, for release alongside its new tablet device earlier this year.
The new promotional image showing an option of opening Keynote on the iPhone suggests that the company may be preparing to roll out an iPhone version of the iWork suite, although the company made no mention of such plans during today's keynote address at WWDC.
Update: Apple has replaced the image in question with a new one, replacing the "Open in Keynote" button text with "Open in iBooks" text.
