Verizon Wireless chief Lowell McAdam today dodged around questions regarding the prospect of an iPhone but put the burden on Apple. At a CTIA press event, McAdam responded to new claims that a Verizon iPhone was being mass produced for early next year by saying that he hadn't seen the specific WSJ rumor but, unusually, said it was Apple's responsibility to announce anything. He warned that this sort of rumor "rolls out every few weeks" but said it was likely just a matter of time for an iPhone or even "a tablet."
