After you give an app permission to auto-update, does anyone know how often it checks for a new version of itself? Does the app check daily and if an update is found (and provided it does not alter the permissions) apply it? Is it possible to alter the frequency that it checks? I ask because I just opened up the Android Market, and right as I did so it suddenly started updating half a dozen apps. Now that was fine, since they all had been given permission to auto-update, but I want to know if they only check for an update when the market is opened, or if it was just a coincidence. Thanks!
