[Updated: Apple issues statement on the matter] Photo gallery service
500px has had both of its photo-sharing apps --
500px and
ISO500 -- removed from the App Store by Apple, the developer
says. The titles are said to have vanished around 1AM Eastern time today. 500px's COO, Evgeny Tchebotarev, has explained that Apple took the move following talks about an updated version of its namesake app, which was being looked at by an App Store reviewer.
