Updates at the foot of the post.
Verizon has flipped the switch on its pre-order page for the new iPhone, allowing existing customers to log into the site using their existing Verizon credentials.
The page has gone live some ten minutes early and is currently taking repeated attempts to fully load the page, presumably as US customers begin to bombard the site to order the new device.
The Apple Store is currently down whilst Apple make the necessary changes, if you are an existing Verizon customer and a resident in the U.S, you can order your Verizon iPhone 4 here.
Update: The Apple Store has now gone live also, you can now buy an iPhone 4 on AT&T or pre-order the Verizon iPhone 4 via the Apple site:
