If and how Apple fixes the notification system tomorrow is anyone's guess. But the above image, courtesy of TechCrunch, seems to suggest something akin to accessing an active phone call from the springboard will be the solution.
Any guess beyond that is an even bigger speculation. This doesn't look as great as we hoped notifications would look like, but it does make sense. Obviously, this could still totally be 'shopped (who knows the who knows, the 11.54pm on June 5 is in the future but the 23C would mean it's a Euro phone) but MobileNotifier, the popular jailbreak app designed by recent Apple hire Peter Hajas, does comes to mind. At the very least, we'll find out more tomorrow. [TechCrunch]
