iOS user can get a FREE 2-Star Lando, or his shards if you already have him unlocked. Like the Droid Event exclusively for Android devices, this event for Apple users only.
To get your Lando follow this link in your Twitter app:
I copied and pasted into a new Tweet from my Twitter app and clicked the link from my Tweet. It's kind of confusing, you can also go to my Twitter page to access the link here. Follow me while you are there! :)
