My phone got stolen, I don't have the find my iphone app installed but I logged into icloud and I can see my phone among the devices but it's offline. My phone can't be turned off because the sleep button doesn't work and the battery was almost full when it got stolen which wasn't that long ago. It does have a passcode but I'm worried sick that the person that stole it has something evil in mind ( like looking at my pictures or my personal details etc.) This happened at school so it's very likely that a teenager stole it and another girl got her phone stolen (our purses were in the changing room and someone went in and stole them). If I remember correctly, I had the find my iphone option turned off in settings because I was trying to save battery and I don't even have the app installed. So I guess my question is can I track it if the thief connects to Wi-Fi or not?
