Sorry users of older iPhones and iPod Touches -- multitasking will not be for you. Steve Jobs says that they don't have the power.
Apple's iPhone, as slick as it may be, has always lagged behind the competition when it came to basic OS features such as copy & paste and multitasking. With copy & paste taken care of in iPhone OS 3.0, Apple announced today plans to tackle the latter feature with iPhone OS 4.0. Yes, multitasking will finally be here in the new software update due to hit this summer.
First, there's good news and bad news. The good news is that Apple claims that its multitasking doesn't tax battery life in a significant way, but the bad news is that only the iPhone 3GS, third-gen iPod Touch and iPad (and newer) will support it. Those still using the iPhone 3G will still get some of the new features, such as the ability to sort apps into folders. Sadly, Apple doesn't list the original iPhone as being compatible with the new software.
iPhone OS 4.0 will be release for phones and iPods this summer, while iPad users will curiously have to wait until fall.
"iPhone OS 4 is the fourth major release of the world’s most advanced mobile operating system," said Steve Jobs, Apple’s CEO. "We’re delivering over 100 new features, including multitasking, folders, a unified inbox, deeper Enterprise support, and an iPhone version of our iBooks reader and online iBookstore."
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
- iBooks reader and online bookstore recently debuted on the iPad
More details from Apple's preview site or the press release:
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. iPhone OS 4 provides multitasking to third party apps while preserving battery life and foreground app performance, which has until now proved elusive on mobile devices.
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. Users can also create and manage iPhone folders on their Mac or PC using iTunes 9.2.
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, and letting users return to their app anytime they choose. iPhone OS 4 lets developers easily embed iAd opportunities within their apps, and the ads are dynamically and wirelessly delivered to the device. Apple will sell and serve the ads, and developers will receive an industry-standard 60 percent of iAd revenue.
The iPhone OS 4 beta release includes a developer preview of GameCenter, 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. Apps created with GameKit APIs will work with GameCenter, Apple’s new social gaming network available to iPhone and iPod touch users later this year.
New enterprise features in iPhone OS 4 include improvements in security, scalability and compatibility. The new Mobile Device Management service can be integrated with third party servers to wirelessly configure, query and even wipe or lock managed iPhones, and iPhone OS 4 enables enterprises to securely host and wirelessly distribute their own in-house developed apps to employees. The new Data Protection feature uses a user’s passcode as an encryption key to protect mail messages and attachments stored on the iPhone. iPhone OS 4 now provides the option to set a longer, more complex passcode, making iPhone and its data even more secure. iPhone OS 4 allows IT managers to set up multiple Exchange ActiveSync accounts, is compatible with Exchange Server 2010 and includes support for forthcoming SSL VPN applications from Juniper Networks and Cisco.
Today, more than four billion apps have been downloaded from the revolutionary App Store and more than 185,000 apps are available to consumers in 90 countries. Over 85 million iPhone and iPod touch users around the world can choose from an incredible range of apps in 20 categories, including games, business, news, sports, health, reference and travel.
Availability
The iPhone OS 4 beta software and SDK are available immediately for iPhone Developer Program members at developer.apple.com. iPhone OS 4 will be available as a software update to iPhone and iPod touch users this summer. A version of iPhone OS 4 will be coming to iPad this Fall.

It will be new and revolutionary because Apple is the first to implement it!
Now that I've seen this I'm even more curious to see the 4th generation iPhone and the new features it will bring. My one wish is a front facing camera but if even the iPad didn't get it I don't think the iPhone will. Have to wait and see.

The title was missing some quote marks...
Multitasking is running several programs at once. They are pausing most of the program with an option to let them use a limited set of instructions when they are in the background.
If you want to know what real multitasking is check out WebOS or any desktop OS since DOS.
Hey genius... the iPhone isn't a desktop OS and doesn't have a massive laptop battery and processor. Question: is it easier to just implement multitasking, or to spend at least over a year developing and brainstorming APIs and an effective solution that (1) eliminates performance and battery issues while (2) providing the vast majority of benefits that multitasking offers? Apple obviously went through the effort for a reason. The goal of the mobile phone is not to be a desktop replacement.
1) You don't know how the battery will be with this multi-tasking, and seeing how the iPhone battery life sucked to begin with, it probably doesn't matter. It doesn't really look like Apple went through a whole lot of extra effort to do this. It's typical Apple to make false accusations at the competition to try and legitimize their lack of features.
"iPhone OS 4 provides multitasking to third party apps while preserving battery life and foreground app performance, which has until now proved elusive on mobile devices. "
As Jobs says, BS. My Droid has been multi-tasking and taking names with excellent battery life.
I hardly see this as innovative. My droid runs tons of apps at the same time all day and has great battery life (better than 3GS by a long shot). Effective multitasking has been out for quite some time now (insert blackberry here) and so has copy and paste and changing wallpapers. I think its hilarious that apple tries to sell this stuff off as new tech, the sad part is the vast majority of the people out there believe them
-1 for being a trolling douche-nozzle.
1. Resorting to personal (and not even brow-raising) insults.
2. Explaining why your phone's battery blows; as if a screen that is only so big and bright because the iphone has no keyboard is a 'feature'. Also...it's called an SD slot buddy.
3. Pointing out that you use your self-built (and therefore obviously not from Apple) PC to handle the stuff your iphone can't currently handle.
awesome...but what damage have you done to Steve Jobs feelings with your comments if dopey117's computer that you're insulting is a Mac. I wouldn't worry though...he/she seems smarter than that.
Hey no fair i wanted to shoot him down!
