Thanks in advance.

The second one looks like the only thing it does is to allow you to access the mobile version through desktop browser, so my guess is that is "faking" the the User Agent of a mobile browser to cheat Google+.

The first one, if it just imports the photos from Facebook and adds them to Google+ it may be using the Picasa api, since it's where Google+ stores the pictures.

Even if you cannot access Google+ api just yet you can use the other Google ones to "influence" what you get in Google+. Just be creative :)

The API has now been announced at: http://googlecode.blogspot.com/2011/09/getting-started-on-google-api.html and the official homepage is: http://developers.google.com/+/
