When I updated my daughters phone, my contacts showed up on her phone and I cant get them off unless I go to each one and delete it.
You'll have to go to each one and delete it. Make sure she has a seperate Apple account from you in the future to prevent this.
Connect her phone to iTunes. Uncheck Sync Contacts and then sync. This will remove the contacts on her phone. Note that iTunes can handle multiple devices under the same Apple ID. Each can have their own sync settings.
Thank you very much.
This is the instructions for managing multiple devices on one computer: http://support.apple.com/kb/HT1495
