How to move magazine subscriptions to newsstand

Actually, it is possible by tweaking the info.plist inside the app's main directory. The Newsstand compatibility is determined by a key named UINewsstandApp that can be set to true or false. However, modified apps will crash on launch unless you have a jailbroken device.

Doesn't make sense. I have Golf Magazine and it went straight to the newsstand. But I also have Front 9, same publisher/same magazine, and I can't get it to the newsstand. What's the deal?

The "deal" is that the app developer decides whether the app goes in NewsStand or not.
