iOS 5 has 1,500 new APIs and over 200 new features, but today Apple showed us the 10 key features of the new software for the iPhone, iPad, and iPod touch. The Notification Center feature alone will make your iPhone or iPad feel like a new device. The developer version of iOS 5 is available today, and the software will be available to consumers October 12. Here’s a quick look at the top new features.
100 billion push notifications and counting tells you that iOS's notification system has scaled well, but they interrupt you and they're not persistent. With the new Notification Center in iOS 5, you'll be able to swipe a finger down from the top of screen at any time on any screen. You close the Center by swiping up, and you can easily dismiss individual notifications with a tap.
The new lock screen in iOS 5 can take you to the app that shows you the notification. This works for anything from Facebook updates to text messages.
