Verizon might have had crazy demand for the 4 because it was the first time an iPhone came to verizon.
I keep telling people asking about lines this.
Last year, iPhone 4 line was BAD.
Little stock, not as much pre-order, and ONLY available at Apple Store and AT&T.
NOW you have reported TONS of stock, TONS of pre-order, and AVAILABLE AT Apple Store, AT&T, Sprint, Best Buy, AND Verizon.
Thats 5 to 2. PLUS in the past year there have been many more Apple Stores added throughout the country helping things as well.
All in all they should not have the problems the iPhone did last year. Just an educated opinion.
