When trying to check for updates from within iTunes for any device, or trying to restore a device in iTunes I click the update/restore button and iTunes opens an explorer window for me to browse to the .ipsw file. I am unable to get iTunes to check the Apple servers for the restore/update files.
Where is this setting stored either in the registry or the iTunes folder?
I have performed a clean uninstall (http://support.apple.com/kb/HT1923) , have removed my apple preferences that were stored in the AppData folders for each user and have reinstalled and still see the explorer box rather than the check apple for updates dialogue.
I have a feeling that the particular setting is somewhere in either the itunes library folder, in the registry or in another plist file... but where is the question?
