Here's a list of changes from their source:
Messaging - The word is that Apple is readying its own MMS / SMS protocol which will be a native part of the phone. We’re not entirely clear on how this would work, but apparently it will be able to automatically identify iOS users and route the message accordingly.
Notifications - Notifications will now be handled in drop down located at the top of the screen (similar to MobileNotifier, seen in the image above). Messages will appear and then slide back up in a unobtrusive manner, similar to webOS. There have been some leaked screenshots floating around the web for the last 24 hours, but those are not the real deal.
Widgets - The notifications will be constantly accessible through a pulldown window which you reach by swiping at the top of the screen downward… just like Android. Not only will this screen house your recent notifications, but it will tout proper widgets like weather, stocks, and more.
Lock Screen - Surprisingly, Apple is making significant changes to the lock screen as well. There will now be notifications shown on this screen with a small icon to the left of each notification — you can drag that icon as you would the unlock slider and you’ll be taken directly to the app itself (similar to TouchWiz for Android). You won’t get weather or stock widgets here, only notifications — and it’s not clear if upcoming calendar events or the like will be represented.
If these changes are going to come in iOS 5, Apple's competition is going to have to play some major catch up. What do you guys think? Credible source or last minute link bait?
