Brian Kim of Proximi wrote in to tell us that BargainBin, arguably the app that coined the term “pocket rejection”, caps off one of the stranger and most memorable weeks in App Store confusion by actually getting out of the pocket and onto iPhones everywhere.

Following up on AMBER Alert’s approval, and Tweetie 1.3′s rejection and almost immediate reversal/approval, we have to wonder if the internet outcry on Twitter and blogs actually made a difference, and something changed deep inside Apple — or if this is just a cosmically coincidental, Ozymandia-worthy joke.

Heh. Maybe Apple’s just trying to get some good faith back from developers before they preview iPhone OS 3.0 and the new SDK on Tuesday…
