I just received an IPad with my Cadillac purchase. I have no idea what IPad release it is or how to find out. My question: I connected the IPAD to my Desktop with Windows 7 Professional 64bit and got the message a driver was installed. What this did is a mystery. I was hoping that the IPad would connect to the internet through this connection. I want to upgrade software and add pdf files to the IPad from both the PC and Internet.
