Apple has revealed the latest version of iPhone OS 4.0. The biggest news about is that it has finally added the Multitasking feature to the iPhone but there is a bad news for those how have iPhones older than the iPhone 3GS because they are not going to get this feature along with some others as well. Apple has added spell check to the iPhone and a User Defined wallpaper option that was one of my favorites on jailbroken iPhones. The event took place at 1-Infinite loop campus in Cupertino and has added a lot of new features for users as well as iPhone app developers as new SDK is now available for download.
One more notable feature is the folders features that adds folders to your iPhone in which you can put apps by categorizing them. They have also added the Game Center feature that includes achievements, leaderboards, and match making. It will be available as a “developer preview,” and out for consumers later this year.
Here are some screenshots of the new version of the iPhone OS
Here are the main features of the new iPhone OS
- Multitasking.
- Spell check
- Bluetooth keyboard support
- User-defined wallpaper
- Tap to focus when recording video, just like with photos, and a 5x digital zoom for the camera.
- Playlist creation and nested playlists.
- App folders for sorting apps! You can even put an app folder in the dock.
- Enhanced Mail! You can have a merged inbox view, switch between inboxes quickly, and sync to more than one Exchange account. There’s also threaded messaging (at last!) and in-app attachment viewing.
- iBooks, just like on iPad, only smaller. You can wirelessly sync books between platforms, a la Kindle.
- Enterprise features, including remote device management and wireless app distribution.
- Game Center. Includes achievements, leaderboards, and match making. It will be available as a “developer preview,” and out for consumers later this year.
Developers are getting plenty of new tricks too:
- New SDK, Now available!
- 1,500 new APIs.
- Background audio
- Background VoIP
- Background location data, both with live GPS for backgrounded turn-by-turn, and cell tower-based for lower power draw.
- Local notifications. Like push notifications, but sends a notification straight from the app without needing a push notification server, perfect for an alarm, for instance.
- Fast app switching. Saves the state of an app and resumes it from where you left off, without dwelling in memory.
- iAd. Apple says it’s for keeping “free apps free.” The ads keep you in the app, while also taking over the screen and adding interactivity — using HTML 5 for video — up to simple gaming in-ad. Apple will offer a 60 / 40 split on revenue, and users can even buy apps straight from an ad.
- In-app SMS.
- Map overlays.
- Quick look for previewing documents.
- Photo Library access.
- Calendar access.
- Full access to the camera.
- Video playback and capture.
- Date and address “data detectors.”
- Automated testing and performance / power analysis (the same tools Apple uses).
