Friend of mine lost her iPhone about 3 mos ago. She didn't have a pass code on the device and didn't have Find My IPhone enabled either. We are on vacation together now and she asked me where all of these pictures were coming from in photostream. I told her they were from her other phone and whoever has it. Taking pictures and then showing up in photostream. Anything that can be done here? She changed her iTunes acct password when the phone was initially stolen/lost. Anything else she should do?
