Restoring ipod touch 4g without updating
First problem occurred - 12-14-12Tried syncing and updating apps on i Pod Touch... Some of the apps in your i Tunes library were not installed on the ipod touch because one or more errors occurred. More problems occurred - 12-15-12I tried syncing the ipod again.i Tunes cannot sync apps to the i Pod "touch" because the apps installed on the i Pod could not be determined. The app "(app name)" was not installed on the i Pod "touch" because an unknown error occurred (0x E800002D)I deleted the apps from the i Pod and synced the i Pod without problem as one forum suggested.
