Last week I connected my iPad Mini to a password protected WiFi network. I purposely did not connect my iPhone. Today I noticed that my phone is using the password protected network, even though I never set it up to use it. Is sharing networks across devices an iOS 7 feature? Or has it been around and I just didn't notice? There are only two other WiFi networks that both my iPhone and iPad have been to and on both of those I had to connect my Mini to the network using the password, it wasn't just magically connected as it was on my phone today. But that was back in iOS 6.
