Those of you rooting for your team have a fun surprise in the BBM Shop. BlackBerry has brought out stickers for quite a few of the teams (but sadly not all) for $1.99 each. Hopefully they are bringing more but I did notice them for Brazil, US, England, France, Germany, Australia, and more. (Confirmed to be Brazil, France, United States, England, Colombia, Netherlands, Nigeria, Argentina, Ecuador, Spain, Honduras, Germany and Australia so far)
BlackBerry is also making a custom BBM PIN card creator to make it easy to share your BBM PIN with your team colors. Check it out at http://mypin.bbm.com/
Thanks Amir for the tip!
