Hi, Yesterday, I had twitter on my iPhone 4S home screen. Today, I do not? I don't remember deleting it, but, it's gone. This has happened to me, in error, with other apps/games, but, I have always been able to go to the App Store and find the app/game "not on this phone" and "install" it. However, in the case of twitter, when I go to the App store, it says that the app is "installed". But, it is not. I've connected my phone to my PC and iTunes and tried dragging the app over to my phone, but, I haven't been successful. So, I tried deleting the app from my iTunes account and then tried to install it again. Still no success. Does anyone know where my app went, or how I get it back? Thanks!
