I found AT&T offers iPhone 8GB refurb for $249. Here is the link. As of now the regular iPhone 8GB is $399 at Apple or AT&T store. I think one has to sign up the AT&T data plan to use some of the web features of iPhone. I could be wrong.
Also, I found this iPhone flip version rumor interesting (source: Sina). I understand the US consumers have a special love for flip phones. I personally switched to the SamSung A437 flip phone lately.
