There is data in the cloud from my old phone, But I can't access it
Hi-
I bought iPhone 6 on day one since the line was not long, but had not backed up to iTunes. The tech at the store said he could put the photos in the cloud. He apparently did since there is 822mb of data listed from my old phone. Now I need a picture from it. How do I access it? I have looked around on my phone and iPad, nothing. I have downloaded iCloud Photos which will allow me to delete photos but not download them and I got a program called Syncios which does see and allow downloading but only for my present iPhone. I live on an island so I can't go to a Genius Bar so you are my last hope... Thank you.
iPhone 6, iOS 8.1.1
