everything is ok and all other apps like IM+ have their own pushes but facebook app doesn't work at all, even when I open the app,push the home button and wait for pushes, I send myself a message,nothing happens.no friends?
sorry. so in (system) Settings you have things enabled. are you on Wifi or in 3G? getting other signals/notifications?
Do you have a Smart Cover (or the like) on it?
Sometimes if it has been "off" for a while with smart cover i don't always get a chime. But if I have been in it recently it will go off.
