I bought a "new" iPhone 3G tonight and paid the $199 price for an 8GB model as a new AT&T customer. I was just starting to play around with it, and went to the App Store to install Facebook, when it prompted me for an iTunes password to install the app. It showed an unfamiliar email address already configured in the prompt, and a blank field for me to fill in with the password matching that email address. This was before I'd even gotten home and hooked it up to iTunes on my home computer, and in any case, it certainly wasn't my email address. Does this mean that someone had already used this phone and set it up with their iTunes? Or, in other words, is this a used/refurbished iPhone that I bought "as new"? Did AT&T rip me off?
