Thank you for your help...but, my problem is the previous owner did not completely delete their information and unlock the iphone 4 before turning it in for an upgrade.....now I am having problems fully activating the phone.
Your iPhone is Activation Locked.
If the previous owner does not unlock it, it will be completely useless to you.
This anti-theft process was put in place by Apple last autumn.
There is no way around it. The previous owner must release the iPhone.
