Shared Photo Stream Won't Appear on iPhone

Hi Apple Support Communities!

I have an iPhone, and before I got a Mac that worked with iCloud's new feature, Shared Photo Streams, I created my own SPS and also subscribed to a friends. When I got the new Mac, I set up Photo Stream.

Today, I realized that my SPS and the one I'm subscribed to will not show up on my phone. They do, however, show up in iPhoto. What's going on? Should I reset my Photo Stream settings for my phone?

All responses are appreciated in advanced.
