I'm trying to upgrade an existing Blackberry account (secondary line on family plan) to an iPhone 4 on VZW, but when I get to the screen that shows all of the upgrades "Apple" and the "iOS" options are grayed out. The site shows all of the other phones that Verizon offers, but not the iPhone. I tried this on two different Verizon accounts and both yielded the same result... I also tried to go to verizonwireless.com/iphone but when I added the iPhone to cart while logged in to the account it just took me back to the Verizon home page. I would rather order from Verizon because of the free overnight shipping as opposed to the 2-3 day on the Apple site. Thanks!
