i have been using the app "installous" to download apps from. i downloaded a few games the other week and all went good. now 2 days ago i went to open one of those games and it was gone.... it still shows up as i downloaded it but i have to re-install the game to make iut show up on the springboard again.. and same thing happended today.. i went to play a game and it was gone. why do they keep deleting them selves from the springboard?
