The iPod U2 Special Edition is a fourth generation iPod with a black front case (instead of white) and a red Click Wheel. On the back of the iPod U2 Special Edition, autographs of all four members of the band U2 are etched along with their printed names: Bono, The Edge, Adam Clayton, and Larry Mullen Jr.
This is the first of three iPod U2 Special Edition devices. The second version was based upon the iPod Color (iPod with Color Display), while the third versions were based upon the iPod Fifth Generation (iPod Video) and iPod Fifth Generation Enhanced. All models feature the same custom colors and engraved autographs.
The iPod U2 Special Edition (Generation 4) shipped with a poster and $50-off coupon for the complete U2 downloadable box set.
I purchased my version of this iPod from a co-worker, and I do not have the original box, poster, coupon, or earbuds.
