Just a moment ago, we reported the new iPhone 4, and now the iOS 4. The first main feature is none other than multi-tasking. Steve Jobs said, “People said you weren’t the first, but we figured it out. If you don’t do it right, you kill the battery.” So, I hope the multi-tasking in iOS 4 will not be a battery hover.
Steve Jobs demonstrated multi-tasking on the iOS 4 himself, he was listening to music plus reading mails plus browsing. The threaded view is also available in mails. Folder creation is also added to iOS 4. You can keep apps of similar category under one folder, like all sports apps under Sport.
The iBooks now, is available for iPhone via iOS 4. The same as in iPad. It will also be available in iPod Touch. Synchronizing the books on your different Apple devices is also possible, like you can synchronize the books on your iPad with your iPhone and vice versa for free. Steve Jobs also introduced iAds, which will help the Apple developers earn money.
