I've been seeing these iPhone commercials for months now. I doubt that they're phasing out "iPhone". ComWave was certainly the one in the drivers seat during that deal, I'm sure they said "give us $xxx,xxx,xxx.xx and let us keep using the name too"
I remember ComWave releasing a statement that "If you ask anyone in Canada on the street what iPhone is, they'll say it's a phone by Apple. We don't like that" or something like that.
