Some of my subscribed Newsstand magazines (The Economist is one of them) use downloadable audio and takes a lot of space. The only way to clear some space to delete app from my Newsstand, install it back, restore previous purchase, download separate issues I want without audio and so on. As my iPhone is jailbroken, I would prefer moving audio on my Mac instead of deleting. Could anyone tell me what folders should I be looking at as so far had no luck finding any apps living on the Newsstand? Thanks.
