Hello friends, I have an iPhone, iPad and a PC. I'd like the photos that I take with the two Apple devices to be synced to one another and also put into a folder on my PC; all done through WiFi. I'm trying out iCloud, but frankly I'm a little confused. In the main iCloud settings menu (in the iphone) there are On/Off switches for a couple things including my Photo Stream (which I take to mean all the photos on my iPhone). Do I also have to turn on "iCloud Backup" in the "Storage & Backup" submenu?
