So I have had annual upgrades for my iPhone for about 4 years now but have lately decided about switching from AT&T to Verizon and have a few questions. 1) Heard ATT has taken out their annual upgrades, so if i were to upgrade to iP5, my annual upgrade won't exist anymore. 2) Does Verizon have one? I read that Verizon has a 20 month early upgrade date as opposed to AT&Ts new 24 months. 3) Is Verizon service really that much more expensive for a base family 2 line plan compared to AT&Ts? 4) I always preorder my iPhone online during the bandwidht crash hours when everyone is trying to preorder theres, if I change to Verizon i won't be able to preorder this on the preorder date right?
