How do I get "tap to tweet" on the pull down menu on my iPhone 4S?
All you have to do is put your finger on top of where the time is (or anything in that black bar) and slide down. if its not coming up on top, try re downloading the app or check for an update on your phone.
It's in settings somewhere.
When you download the app it should automatically show up. Otherwise you might be able to add it in settings
