My iPhone is being linked to other devices?

Me and my parents are all under the same iTunes account so when I buy a song on my iPhone it goes on my parents devices as well through Wi-Fi. I now have a new SIM card and a new number for my iPhone so texts sent to my phone are being sent to my parents as well. How do I stop this?

Call apple and ask

  • My iphone 4 is linked to someone's ipad? So i just recently got a iPhone 4 for Christmas, and these children in my neighborhood have iPads from their school, and for some odd reason i'm linked to one of them?
