I took my iPhone to the Apple store because I was having screen problems with it and they replaced it with a new one and I stored an iCloud backup on my new one all my data is on my new iPhone.But for some reason my old iPhone is still linked to my iCloud.And I have been hearing that if you unlink the device for the iCloud it will delete all the data off of the device.I know that if you unlink an iPhone or other Apple device it will delete the data off of iCloud but if I was hearing is true if I unlink my old iPhone off of my iCloud then will it delete all the data of the backup stored on my new iPhone?If it does then can I restore my new iPhone from an iTunes backup?
