This is the first app I've tried to install, and i'm not having much success.

I've transfered it over to the iPhone, according to instructions, but it's not showing up on the phone.

Could the fact that I've replaced the springboard icons, and changed their display order be the reason it's not showing up?

Any help is much appriciated

Make sure that it is executable.

I did the ssh command to executefy it

I actually installed my Lights Off via Fugu and changed the permission there. Was way easier. There seems to be some issues with Lights Off being two words. Once your have cd /Applications try to chmod +x "Lights Off.app" or try chmod +x Lights\ Off.app or use Fugu or install MobileSquid and try that.

from ssh use the ls command on your /Applications folder to make sure that Lights Off is there.

I have included the Lights Off DisplayOrder string below. Add it to your plist wherever to ensure that if its there it will show.

<dict>
<key>displayIdentifier</key>
<string>org.deliciousmonster.lightsoff</string>
</dict>
