"How can I ensure that all of my photos and info transfer to my new iPhone?: I have iCloud storage that I haven’t backed up my most recent photos. I purchased a new phone and I’m afraid only my photos on my iCloud will transfer. What can I do so all of my photos and information transfer to my new phone. Thank you."
