I realize now how the green indicator might be misleading in this case. It simply lists the number of devices connected, not whether they are provisioned.
Have you added your iPhone 5 to your provision? You may need to go to the Apple iOS Provisioning Portal, modify your existing provision to include your new device (and register the device with the Portal if necessary) and import the modified provision in Icenium, replacing the old one.
