minieleven theme add widget before footer

I want to add a widget before the footer in the minieleven theme.

Currently I can add only a widget after the footer by using code similar to the following in a plugin.

// Check if we are on mobile
    function jetpackme_is_mobile() {

        // Are Jetpack Mobile functions available?
        if ( ! function_exists( 'jetpack_is_mobile' ) )
            return false;

        // Is Mobile theme showing?
        if ( isset( $_COOKIE['akm_mobile'] ) && $_COOKIE['akm_mobile'] == 'false' )
            return false;

        return jetpack_is_mobile();
    }

    function jetpackme_after_footer( $content ) {
    	// widget code
    	echo '<div class="footer-widget"></div>';
    }

    if ( jetpackme_is_mobile() ) {
    	add_action( 'wp_footer', 'jetpackme_after_footer', 10, 0 );
    }

However, I want to add a widget above the footer, so that it would look like this:

</div><!-- #wrapper -->

    <div class="footer-widget"></div>

    <footer id="colophon" role="contentinfo">

If there was a hook before the footer similar to the following, then we can easily add a widget before the footer

</div><!-- #wrapper -->

    <?php
    	/**
    	* Fires before the footer
    	*/
    	do_action( 'jetpack_mobile_footer_before' );
    ?>

    <footer id="colophon" role="contentinfo">

By adding this hook we can use the code similar to following to add widget before the footer

function jetpackme_before_footer( $content ) {
    	// widget code
    	echo '<div class="footer-widget"></div>';
    }

    if ( jetpackme_is_mobile() ) {
    	add_action( 'jetpack_mobile_footer_before', 'jetpackme_before_footer', 10, 0 );
    }
