I had my iPod Touch and created an apple id account. When i bought iPad4 i sold the iPod Touch but i used same apple id that was registered in my iPod. Will there be no conflict at all with regards to application, photos and updates since I am now using an Ipad? Now the iPod was reset and used by another user name. does the new owner of Ipod can still access my info? please help, i am worrying of the security and privacy. Thank you.
