More promise like syntax:
```js
    it('should toggle the airplane mode twice', function (done) {
      driver
        .getNetworkConnection()
        .then(function (type) {
          var newType = (type % 2) + 1;
          return driver
            .setNetworkConnection(newType)
            .getNetworkConnection()
            .then(function (updatedType) { return updatedType % 2; })
              .should.become(newType % 2)
            .setNetworkConnection(type)
              .should.become(type);
        }).nodeify(done);
    });
```
