Pepsi in the US is giving away 100 million free songs from the iTunes music download site. (You may remember they launched the campaign during the Superbowl using people who had previously been sued for downloading songs illegally). It seems Pepsi hasn’t quite got it right:

“One in three bottles is a winner, but it turns out that the markings can be read without removing the cap. Not only is it possible to pick out winning bottles in advance, but careful scrutiny can reveal the full 10-digit redemption code, meaning that no purchase is required to get a free iTunes single, courtesy of Pepsi. “

Oops.
