This is still very much a rumor at the moment, but according to the rumor, Landor Associates is busy working on an advertising campaign for Verizon regarding the upcoming iPhone. Could this be a hint that the iPhone 4G could be hitting Verizon? Landor Associates has already been working on Verizon’s branding since back in 2007, so it wouldn’t be surprising to see them partner together again. The question is, in light of AT&T’s 5-year deal with Apple, could this still be true, or is it just another Verizon iPhone rumor that refuses to die off? Just in case you aren’t familiar with Landor, the company works with many big name clients such as Citibank, FedEx, and RIM.
