I don't like very much iterator's semantic, please consider this as an option. It's also safer as you publish less of your internal state

private Map JSONtoMAP(String jsonString) {

    JSONObject json = new JSONObject(jsonString);
    Map outMap = new HashMap();

    for (String curKey : (Set) json.keySet()) {
        outMap.put(curKey, json.getString(curKey));
    }

    return outMap;

}
