Update with ad after the jump Cisco has delivered a full-page ad promoting its version of the iPhone, according to news from the New York Post. The ad, which appeared in the Thursday issue of the New York Times, heavily promoted the networking company's recent Linksys-branded iPhone in a conspicuous attempt to reinforce its belief that it holds the legal rights to the iPhone name.

The posting was unusually well-timed, appearing the same day as Apple and Cisco together extended time to respond to the latter's lawsuit over alleged trademark infringement. Apple has so far avoided extraordinary tactics, stating only that it thinks the Cisco suit "silly."
