New Features for iPhone OS4
Apple today previewed its iPhone OS 4 software with over 100 new features that will be available to iPhone and iPod touch users this summer. New features include Multitasking for third party apps; Folders to better organize and access apps; improved Mail with a unified inbox, fast inbox switching and threaded messages; enhanced Enterprise support with even better data protection, mobile device management, wireless app distribution and more; Apple’s new iAd mobile advertising platform; and iBooks, the new ebook reader and online bookstore recently debuted on the iPad.
iPhone OS 4’s new multitasking offers users a new way to quickly move between apps, and provides developers seven new multitasking services to easily add multitasking features to their apps. These services include background audio, so apps like Pandora can play music in the background, and VoIP, so VoIP apps can receive a VoIP call even when the iPhone is asleep or the user is running other apps.
Folders help users better organize and quickly access their apps. Simply drag one app icon onto another, and a new folder is automatically created. The folder is automatically given a name based on the App Store category of that app, such as “Games,” which the user can easily rename. Using folders, users can now organize and access over 2,000 apps on their iPhone.
iPhone OS 4 delivers the best mail experience on a mobile phone with its new Unified Inbox, allowing users to see messages from all their email accounts displayed together in a single inbox. With just a few taps, users can quickly switch between inboxes to see messages from any single account. In addition, users can now thread their messages by conversation, making it easier to stay on top of email discussions, as well as open email attachments with compatible apps from the App Store.
iAd, Apple’s new mobile advertising platform, combines the emotion of TV ads with the interactivity of web ads. Today, when users click on mobile ads they are almost always taken out of their app to a web browser, which loads the advertiser’s webpage. Users must then navigate back to their app, and it is often difficult or impossible to return to exactly where they left. iAd solves this problem by displaying full-screen video and interactive ad content without ever leaving the app.
The iPhone OS 4 beta release includes a developer preview of Game Center, which contains a set of APIs that allows developers to create apps with the ability to invite friends to play a game, start a multiplayer game through matchmaking and track achievements and compare high scores on a leader board
