I haven’t seen this reported anywhere else… unlocked my iPhone 3Gs running iOS4 a few moments ago and was presented with a series of notification panels. As I cleared each one, a new one popped up. This is certainly a better solution than the previous model of listing the most recent 3 notifications on a single panel and ignoring the rest. At least I can now respond to each. It’s not as nice as the sliding panel in Android, but it’s certainly a step in the right direction.
