If you access GenieGO™ through an iPhone or iPad, please be sure to update your GenieGO™ App before upgrading to iOS 7. This will ensure no interruption to your service. You can update your App anytime through the iTunes App Store.
If you have already upgraded to iOS 7, you will need to update the current GenieGO™ App on your mobile device and then re-register the device as new. Unfortunately, previously downloaded content will need to be re-downloaded.
We apologize for this inconvenience.
