please please help me with this i cloud
please please will someone help me!!!! I cant understand this i cloud. Basically I have the i phone 4s that used to be my brothers even though its all set up under my dads details. My brother now has a new i phone and I have his old one. Every time I take a picture or send or recieve i messages my brother sees it all on his phone we both have our own apple ID'S but when I look under this 'i cloud' its under an email and password for my dad, It says delete account but then I'm scared I will lose all my photos and contacts but at the same time I cant carry on like this sharing everything . How can I stop us linking togeter with my own account but not lose everything... Thanks :'((
