Yes, up to 10MB then it costs. Saw it online somewhere today
Just checked the website:
"Now it’s free to blog, post, or tweet from your seat on most of our A380 aircraft. Enjoy 10MB of data for free, or buy 500MB for just USD 1. Three of our A380s don’t have free Wi-Fi yet. But you can buy 500MB for USD 1 on these planes, and also on select Boeing 777s.**"
