Is there any way to see if you already own an app without having to click "buy" then sign in (cross fingers) to find out I have already paid for the thing? If not then I just purchased it any how sooooooooo that seems to be a bad idea. Also, is there no universal "sound off" switch that all apps obey? Why would Apple allow an app developer to choose what the sound on/off toggle switch does? I have a few apps that always play sound no matter which position the toggle is at, quite frustrating when you are trying to be discreet on the crapper at work!!!!
