So I have my new iPhone 5 and my old 4 just sitting there. I reset that few hours ago and will sell it to my friend. So the question is, look at the screenshot. My iCloud has 2 backups, one from my old phone and one on my current 5. Can I safely delete the old backup without losing any data on my 5? The black is my 4 and white is my current 5 that I'm using.
