Do we know how iPhone OS 4 will handle apps that are lumped into folders and have badge icons (via push notifications or otherwise)? I'm hoping there will be an option for the folder to have its own badge icon that sums all the badge icons in the folder. It would be nice to lump applications that get badge notifications into one folder. This would at least provide some form of notification management until Apple solves the problem. Granted this won't work for applications that use the badge icons for things like temperature. Thoughts?
