Verizon this weekend stepped up the pressure in its anti-AT&T campaign with three new ads (viewable below). The lead ad, "Misfit Toys," attacks the iPhone's attachment to AT&T and says it belongs on Rudolph's Island of Misfit Toys for running on a network with relatively low 3G coverage. Unlike the recent Droid ads, the new commercials take care to praise the phone but attack the network, suggesting Verizon is backing away from direct criticism of Apple.
