Verizon is taking rival Alltel to court, asserting that they are guilty of false advertising that portrays Verizon in a negative light. Verizon states that claims made in Alltel commercials, such as only Alltel offering the ability to change calling plans without extending contracts, are false.
This lawsuit is a follow up to a cease and desist that they issued to Alltel. The reasoning for it is because originally, Alltel was right - when the commercials were originally aired, Verizon did not allow changes without contract extensions. That has since changed, however, and Verizon is angry that they have not updated their advertising to reflect this. It isn't mentioned what Verizons claims are, but you can bet that they will demand scads of money.
