Waiting for that Tweetbot elusive iPad update.......
Update: Twitterrific has stopped working over LTE for me and I am unable to send or receive tweets. The app works when on wifi. I will have to delete this app on the iPhone until the Iconfactory has a solution to get it working again. I have tried force quitting the app and deleting and re-installing it.
Update 2: Finally figured it out. The cellular data setting was turned off for Twitterrific which was causing the app to not retrieve or send data over my LTE connection. Once I flipped the switch to enable data, the app worked like a charm.
