Apple is conducting a massive PNS (Push Notification Service) test again. This time with AIM, AOL's (or MobileMe) instant messaging app. More like it, as this is interactive and much more meaningful using PNS. Below is what it looks like:
a) You can see an IM message sent from me via the Alerts and Badges.
b) This is the Alerts shown when the iPhone is locked. Notice the unlock slider says, "slide to view". When you slide, the app automatically launches immediately after unlocking; no, the app does not launch until you take this action. (I'm not sure if this is an improvement over the previous AP News app or something that is controlled by the app developer. Or maybe I just missed it…)
c) If you don't want the app to automatically launch when you slide, you can ignore it by pressing the power/sleep button. Turning the iPhone back on shows the regular "slide to unlock".
Previously, I complained that after receiving the notification, you still have to launch the app and it was annoying, especially due to the time it takes. But if the iPhone 3G S is truly faster at starting an app, it might not be such a big deal. We'll see about that…
