I can only speak on the App for an iPhone4 (running IOS 5.1) but they're all probably similar...Open the app and at the bottom right there should be a button that says "More." Click on that. On the next page, click on "Subscribed." Once the next page opens, anything in a bold font is a new post to a thread you're subscribed to. Hope that helps!
