On my jailbroken 3.0 ipod touch 1g, when i try to download apps from the appstore they do not work. In the app store the green install button stays clicked, and does not exit to the homescreen. when i press the home button to go to the sprringboard, there is an app that is trying to be installed, it remains at zero progress, and its not downloading anything. i thought it was the one app, so i tried it on another app, and so far all three do the same, and now i have three installing icons, all that arent installing. any ideas?
