I was just going to tell you that. . . had to step another Freeper through that Friday. It's not really an invasion of the iPhone but just a hijacking of the webpage and using the ability of the browser to reload the webpage to the last webpage you were on. They want you to pay them $100 to solve it for you. It is very frustrating when you don't know how to do it. I also recommend doing a full cold restart and memory clear by holding the home button and power button for 10-15 seconds.
