Just less than a week after releasing the Wi-Fi version of the iPad, Apple announces iPhone OS 4.
As listed on Apple’s Web site http://www.apple.com/iphone/preview-iphone-os/ –
Get a sneak peek into the future of iPhone OS.
On April 8, Apple unveiled plans for the biggest and most exciting iPhone software update yet. iPhone OS 4 will include over 100 new user features for iPhone and iPod touch owners to enjoy. And for developers, a new software development kit (SDK) offers over 1500 new APIs to create apps that are even more powerful, innovative, and amazing.
iPhone OS 4 will ship this summer for iPhone and iPod touch, and for iPad in the fall. A developer beta is available now.
Among the 1500 new APIs and 100 new features are –
Multitasking (run multiple apps at the same time)
Folders (for better organization and screen use)
iBooks (the iPad bookstore comes to the iPhone)
iAd (Apple enters the advertising ring for in App ads)
Just like iPhone OS 3.0’s Voice Control and digital compass, some features won’t work on all iPhones. For example, multitasking will only work on the iPhone 3GS and iPod Touch 3rd Gen (late 2009) 32 and 64 GB models.
