But now I think I understand the griping of @alanquatermain a few weeks back. From the timing, I think that he had just gotten the Borders app approved when Apple started being difficult about the Kobo app. The apps are largely identical, so there was no reason for one app to be approved and the other denied.
Yeah, I just checked and I cannot create an account in the app (just log in to an existing one). Now his griping makes sense. Apple approved features in the Borders app and then turned around and blocked those same features in the Kobo app.
Oy. I've called Apple capricious (only Steve knows what they'll do next), but this is a new one.
