Apparently the negotations mentioned yesterday broke down.
"Cisco sued Apple for trademark infringement over the "iPhone" name Apple chose for its new cellphone, unveiled yesterday. Cisco obtained the iPhone trademark in 2000, and had been in talks with Apple over rights to the name.
"Cisco entered into negotiations with Apple in good faith after Apple repeatedly asked permission to use Cisco's iPhone name," said Mark Chandler, Cisco's general counsel. "There is no doubt that Apple's new phone is very exciting, but they should not be using our trademark without our permission."
The article is at the Wall Street Journal if you have an account.
Looks like Apple is either going to be paying some fat royalties... or renaming the phone by June. Of course, with Cingular planning to rename over to AT&T, perhaps Apple and Cingular can have a renaming party. :)
