Next-generation iPhones likely to focus on internal improvements.
iOS 5 Beta 2 Notification Center Now Shows Upcoming Calendar Events
One small but notable additional feature that we've been made aware of is the addition of upcoming calendar events on the Notification Center.
Apple's Notification Center is a centralized view of all your push notifications and widgets. A simple swipe from the top of the screen brings the notification center into view. See this video for the Notification Center in action in both portrait and landscape mode.
In the latest beta, Apple has also included calendar events for the upcoming 24 hours in the view, so you can see easily see your calendar appointments at a glance. There are no settings yet to adjust how far in advance you can see your events. Apple has announced it will be releasing iOS 5 to the public this fall.
