var map = L.mapbox.map('map', 'mapbox.streets', {
    tileLayer: {format: 'jpg70'}
}).setView([37.7762, -122.4299], 13);

// If you wanted to add tileLayer after L.mapbox.map, use:
// L.mapbox.tileLayer('examples.map-8ced9urs')
//    .setFormat('jpg70')
//    .addTo(map);
to create your own custom map and use it in this example.
