When I tried to update Facebook it vanished, same with Twitter then Appworld. When I was managing to download apps before what happened with Facebook they would never work when installed (but themes would). So now I have no appworld etc. Have tried updates directly from internet but the icons are nowhere to be found but if I go into device menu through options it says in Applications that they are installed but they are nowhere to be found. My carrier told me I had a software fault and the version I had was out of date but nothing I do will update it.
