I just attempted to install the installer.app update and after the download there was an error. (Unfortunately I don't recall what it said). As a result, installer.app is apparently gone from my iPod so I can't install or uninstall any more apps. Is there any way of bringing the app back without restoring and re-Jailbreaking it? On a side note, when connecting to my iPod touch with SSH, the installer.app is still in the applications folder. Would it be possible to get the icon back by altering the N45AP.plst file?
