Apple may be agreeing to give out subscriber info to get magazines in the iBookstore and on the iPad, a rumor on the latest episode of TWiT suggests. Controversial Mahalo head Jason Calacanis heard from a "major publisher" that Apple CEO Steve Jobs has acquiesced to giving out an unspecified amount of customer data after the publisher refused to offer subscription content without circulation info. It's not known if any other publishers put down a similar ultimatum.
