You're holding it all wrongI remember switching from Sprint due to a horrible customer service experience and going to AT&T for the original iPhone back in Feb 2008.
I remember after the 3GS released in 2009 the iPhone commercials showing off being able to talk on the phone via while surfing the web to look things up via 3G and touting "can YOUR phone on YOUR carrier do that" which was clearly aimed at VZW and Sprint since phones could not do both at once via CDMA.
I remember the antennagate fiasco shortly after the iPhone 4 dropped and Apple holding a special event conference for SJ to take the stage to explain/defend. Was it due to the iPhone 4 antenna design or due to AT&T's network?
I remember VZW finally getting iPhone 4 in early 2011 and Spring joining in at the release of iPhone 4S in fall 2011.
