What's photo stream on iPhone 5?

I got an iPhone 5 yesterday and my sister has a 4 and some how on whatever photostream is it gave me her photo like I have no idea how? Does anyone know?

Photo Stream is what it sounds like. A stream of photos that are synced wirelessly among iOS devices. If both iPhones are signed into the same Apple ID that is what will happen, the photos will be synced between both.

  • Why do I have photo stream on my iPhone? I realized others with the same IPhone I have have 'Places' instead of 'Photo Stream.' Why is this? I want to get rid of Photo Stream if possible and just use my Camera Roll.
  • What is photo stream on the iPhone? Hi so I just recently got an iphone! I went for a few weeks without using iCloud but then I recently decided to get it. I noticed under my pictures that there's a new tab with "photo stream" and only the pictures that I took after I used icloud? What is that? Does that mean only my pictures that I took after I got iCloud will be on iCloud?
  • What does turning off photo stream on iPhone do? If I turn it off will it still put my pictures in photo stream and other people can see them? Or will it just like not put my pictures in photo stream anymore for people to see?
  • Taking photos on iPhone to appear on another iPhone's photo stream? I'm going on holiday and don't want to take my iPhone 5c as it might get damaged/lost etc. So I want to take my old iPhone 4 just to take pictures on it. I was just wondering if there was anyway so when I take a photo is automatically appears on my iPhone 5c's photo stream back home? (This is just incase I lost my old photo - which wouldn't matter too much since it is extremely slow)
