I ended up doing this. Seems to work:

import React, { Component, PropTypes } from 'react'
import { browserHistory, Router } from 'react-router'
import { Provider } from 'react-redux'

class AppContainer extends Component {
    static propTypes = {
        routes : PropTypes.object.isRequired,
        store  : PropTypes.object.isRequired,
        loaded : PropTypes.bool.isRequired,
    }

    constructor() {
        super()
        this.state = {loaded : false}
    }

    componentWillMount = (nextState, replace, callback) => {
        const { routes, store } = this.props
        store.dispatch({type: 'GET_JSON_DATA', cb: this}) <--- include 'this' so I can call isLoaded() from my data-service actions
    }

    isLoaded(){
        console.log('isLoaded')
        this.setState({loaded: true})
    }

    shouldComponentUpdate () {
        return true
    }

    render () {
        const { routes, store } = this.props
        if(this.state.loaded){
            return (
                <Provider store={store}>
                    <div style={{ height: '100%' }}>
                        <Router history={browserHistory} children={routes}/>
                    </div>
                </Provider>
            )
        }else{
            return <div></div>
        }
    }
}

export default AppContainer

and in my data-service actions:

....
return axios.all([getPosts(), getPages(),getJobs()])
                .then(axios.spread(function (posts, pages, jobs) {
                    console.log('STORE LOADED')
                    action.cb.isLoaded() <-- I call the function isLoaded() in AppContainer.js
                }));
...
