The following tutorial assumes that your device is rooted.
1. (Optional) Backup your device
2. Download a file manager (CM10 includes ones) and allow it superuser permissions. (You must be rooted)
Settings>general settings>Access Mode>”Root Access Mode”
4. Open the “build.prop” file and find “ro.product.model=” - insert the appropriate product model, in this case “SGH-I747M”. Make sure to save the file.
5. Exit the application and restart the device, Mobile TV for Bell and Virgin Mobile subscribers should now be working!
This method will work and applies to all kinds of devices assuming whatever application you are trying to execute reads from the "build.prop" file.
