So my local Apple Store has not been carrying ANY iPhone 4 cases due to the free case program, which ended recently. I went there last night and their selection of cases was very small. They also had no bumper cases! Even on the online Apple store, all the bumpers are listed as "currently unavailable". I would've thought that they would have a fairly large inventory of bumpers considering that the free case program only allowed you to get a black one. What's the deal??
