For all device registrations, you must get the new Device ID. The ID that is shown in iTunes will no longer work for our licensing system.

There are two options to get the new ID:

1. From the guiDesigner Upload Service window
   1. When attempting to load a GUI onto the device, the guiDesigner Upload Service will show the new Device ID of the device that you can copy/paste for registrations.
2. By loading a dynamic GUI following the steps below, and having the new ID emailed to you.

Please follow these steps to retrieve your Device ID:

1. Install iViewer4 on the device
2. Go into 'Settings' on your iOS device and find 'iViewer4' in the application list
3. Select iViewer4 and in the GUI File URL, enter 'emailid.commandfusion.com'
4. Then ensure 'Reload GUI Layout' is enabled
5. Launch iViewer and it will load up an interface for you to enter your email address
6. Enter your email and press the 'Email Device ID' button
7. You will then receive an email containing the new Device ID you must use when registering your device.
