Which version of graBLOX do I have?

This is an easy one. Here are two ways of finding out:

1) On my Android phone, from the home screen, I hit the bottom left touch-button to bring up a menu, and then I hit Settings->Applications->Manage Applications->graBLOX, and near the top of the screen it says “Version 2.2″.

2) From within the graBLOX game itself, go to the world-select menu (where you can select which world to try), hit the “i” at the bottom of the screen, hit “email support” (don’t worry — this will not send an email immediately!) and then scroll down to the bottom of the partially-written email and note that there’s a few lines of data, the top one of which says your version of graBLOX.
