iPhone to Verizon January 2011

Business Week: “Verizon Wireless, based in Basking Ridge, New Jersey, will begin offering the iPhone on its network in January, ending the exclusivity AT&T has held since the deviceâ€ s introduction in 2007, two people familiar with the plans said this week.”

I’ll be interested in two things: 1) How many folks will convert from AT&T to Verizon on day one, 2) How well will Verizon’s network hold up under the new strain?
