You've received an erroneous email about a "patriotic can" that Pepsi allegedly produced with an edited version of America's Pledge of Allegiance.  The truth is, Pepsi never produced such a can.  In fact, this is a hoax that has been circulating on the Internet for more than four years.  A patriotic package used in 2001 by Dr Pepper (which is not a part of PepsiCo) was inappropriately linked to Pepsi.  Details of the hoax can be found at http://www.snopes.com/politics/business/undergod.asp.

Thanks for giving us the chance to clarify the situation and please feel free to share this note with anyone else who may have received the message.
