In order to transfer game data from one Apple device to another, simply sign in to the same iCloud account on both devices.

Once iCloud is enabled and available, your game saves will be automatically backed up and stored in the cloud, ensuring that you can access them on any device signed in to your iCloud account. That means you can seamlessly switch between devices without having to worry about losing your hard-earned progress.

However, it's important to note that both devices must be connected to the internet at all times. This is because the game progress is stored in the cloud, and if you play offline, the saves on one device might overwrite the saves on the other device.

NOTE:  There is no version of Jetpack Joyride 2 that is being supported on Android at the moment.
