What should I do about stolen iPhone?

My mother and her ex are engaged in a nasty split. They have children and he is being extremely difficult. Ok that is between them but in the summer my sister picked me up inn her fathers car (the ex) and I know I left my iPhone. I asked her but it was not found and that was in June. Fast forward and I learn that the ex has my iPhone and he became biligerent when my sister attempted to get the cell for me. Needless to say but we have different fathers. Now what should I do about getting my phone back? I called and the guy didn't answer my call. I find this weird and very distrubing. I need my phone. Any suggestions? Plus my mother is passive and she said "forget the phone he will lose his" I have pictures and texts that I would like to have.

If you used your apple id on your iphone then you can simply lock it remotely or wipe all the data off it. You can even leave a message for people to return it to you. To do that simply click the link below and enter your apple id, click on find my iphone and follow the procedures and it will locate your iphone for you. Once it is located on the map, click it and it will give you these options.

Ilostfinder is great.
