I've got a strange problem with my iPhone 4, which I didn't notice until after I had set up my iPad. It seems that apps on my iPhone aren't sending notifications to the lock screen/notification center in most cases (I noticed this when notifications started pouring through on the iPad but I got nothing--no lock screen, no notification center, no badge, no nothing-- on the iPhone. I've checked the notification settings for the apps and they mirror the iPad: Notification Center, Badge App Icon, Sounds, and View in Lock Screen all ON. Sometimes badges work, sometimes they don't. It seems that badges only consistently appear on the app *after* I've opened it. I've tried doing a restore on the iPhone, but it seems to have not made any difference. Has anyone experienced anything similar?
