From the leaked Windows Phone 8 emulator we know that users will be able to select up to 5 apps to show small notifications on the lock screen.
Official press photos for the Nokia Lumia 920 for the first time shows examples of such notifications, with notifications for a Skype and AP app both showing up, in addition to the email notifications.
Microsoft is still to officially reveal consumer features of Windows Phone 8, with the latest rumours suggesting an official reveal 7 weeks from now, on the 29th October.
