Verizon Offers iPhone 4 (Feb. 10): Verizon begins offering the iPhone 4, giving consumers an option other than AT&T, and fueling the rivalry between the two wireless carriers. Recent reviews of the Verizon iPhone have found that it drops fewer calls than the AT&T version. Customers in N.D., S.D., Mont., and Wyo., which are not currently serviced by AT&T, will now be able to purchase an iPhone from Verizon.
