Hi Kyle,
It could be an Xcode simulator only issue. I would be curious to know the versions of:
Mac OS X
Xcode
iOS SDK
If you are interested in further troubleshooting, you could debug the web traffic when running the simulator, and see if any of the requests throw an error. You can do this with Fiddler running on a PC, or with Charles, which can run on a Mac.
Here are some resources:

Hope this helps!
