Hi i'm an italian Apple user since 10 years and i never had a problem with its devices until now. In these last two weeks i've seen dozens of unknown photos appearing in my Photo Stream folder. So in my Iphone 4 (firmware 5.1.1) and in my Macbook Pro (OsX 10.8.1) i've these photos of a stranger. One of these photos is a snapshot of the iphone settings-> general-> Info panel. So i know that he is an italian iphone 4s user ( model MD235IP) (Line provider: Vodafone IT 12.1) and is using this version of iOS: 6.0 (10A5376e). i've called Apple today and i gave them the serial code of the stranger's device. They told me that there is nothing they can do and that i can just change my AppleID password. I've changed my pswd but right now i've received other two not-mine photos on my Mac and in my Iphone. SO what i have to do? i've never shared my personal photos and i can't think that this stranger can see my photos. PLEASE HELP! I know that maybe you don't believe me but i'm telling the truth. if you want i can give you the settings snapshot of this stranger and any other information.
