I'm attempting my own Live Listen iOS implementation too. Can anyone shed light on how to accomplish it? I know it can be done as Chatable, Fennex, and a few others have it. Thanks in advance.

Of course, I figure it out shortly after posting the question. The issue was NSUbiquitousContainers entry in info.plist was wrong when I first ran the app. I fixed it and re-ran. But, the entry is only reloaded by iOS when the build number changes. Bumping that and now it's working fine.
