AT&T has an incredible offer for the post-Christmas shopping season: a refurbished iPhone 4 unit (16GB) for $99. You’ll find it on the carrier’s website, that also displayed a $79 version with minor aesthetic defects, but that disappeared from the site.

There’s also the 32GB iPhone 4 for $199 or $179, with the “cosmetic blemish” one should expect. These refurbished models are tested before they’re resold, so there’s no problem with them. Also, one should remember that the special prices only apply through the AT&T website. Are these the lowest prices possible for the iPhone 4?
