Inside iOS 5 Beta 2: New lock screen notifications, slide away keyboard
The second beta of Apple's iOS 5.0 mobile operating system began making its way to developers on Friday, revealing cosmetic changes to certain lock-screen notifications, a slide away keyboard in iMessage, and other tweaks.
As previously discussed, users of iOS 5.0 this fall will be able to select between two distinct styles of notifications: traditional "Alert" notifications that overlay the screen (as they do in iOS 4.0) and require the user to dismiss them, and new "Banner" notifications that appear subtly at the top of the screen for a few seconds before rolling out of view and into the Notifications pull-down without any interaction.
