The official launch of BlackBerry 10 in the U.S. will be happening in the next couple of days (event tomorrow, AT&T availability on Friday). To celebrate, BlackBerry has made this awesome GIF and it's designed specifically to work on BBM.
To save it from a PC, just right-click and Save As. You can then send it yourself and set it as your BBM profile picture. If you're on the BlackBerry 10 browser, just press and hold on the picture and click the Save Picture icon.
Welcome to the U.S., BlackBerry 10!
