this is where i read the alternative solutions this:
http://thebigboss.org/2008/10/30/tip...-hidden-icons/
it says:
If you cannot install anything because Cydia is hidden, you can use apt-get install quickgold from the SSH prompt. In the most drastic case where you also do not have SSH, you can use iphone browser and delete the file located at /var/mobile/Library/Preferences/com.apple.SpringBoard.plist. Then reboot.
i don't know what any of this means or how to get "apt-get". does this make sense to you?
