I want to cancel my Go Phone prepaid plan. I activated my iPhone using the 999-99-9999 trick for the social security number. Following one of those tutorials too closely, I put in "John Doe" for my name. I activated my iPhone this way to use my iPhone as an iPod. I want to know how the cancellation process goes. The online account details says my cancel date is February 7th, 2008. I assume there's a way for me to call AT&T to tell them to cancel my account now and not pay for more service.
