Handling/parsing JSON data from registerForPhoneAppMessages possible?

Hello,

I'm trying to parse JSON information received from a companion phone application in the following JSON format but can't seem to find something to help me parse JSON. The JSON data isn't too complex, but is there something to help convert this information to a Dictionary (with nested dictionary as values)?

I see the Communications module has options for JSON for http requests, but is there some code or help for doing this for non http requests? Or is it recommended to use some other communication format between a watch app and phone? Maybe simple comma separated values? 

I'm a bit new to Monkey C, so any help/guidance is much appreciated.

}

Thank you for your time.
