Using my regular AppStore account on the iPad 2
I just got a brand new iPad 2. I wanted to get the iBooks. I was asked to either create a new account or use an existing one. So I thought of using the one I already have and use with my iMac.
All the information was there excerpt for one thing: I am asked to enter a security code. Since I do not know which code they are talking about, I click on go 'here', a window open and stays completely blank.
My questions are the following:
1) What is this code? Where do I find it or where can I get it?
2) Else, I tried to find a way to cancel the use of my existing account on the iPad so I could create a new account, I was unable to find how to do it.
Any suggestions will be most welcome.
