More rumors have surfaced that iOS 5 will include a revamped Notification system and include Widgets. This new update will supposedly be announced at WWDC next month. It has been rumored for some time that Apple should and will revamp their notifications system. The notification system in iOS really does need the revamp to catch up to the notification systems in platforms such as Android.
Now nothing has been announced by Apple yet and we won’t hear anything else besides rumors until WWDC but we can predict what the widgets will be like. I can only think that they will be much like the dash board widgets already present in Mac OS X. These widgets will provide quick access information that will be available on demand and load much quicker than an actual App.
