Apple COO Tim Cook:
CDMA doesn’t really have a life to it after a point in time.
The longer that Verizon squeezes its customers for each nickel and dime, and disables hardware features that OEM’s build into handsets, the longer they go without an iPhone in their lineup. Even with the transition to 4G technology (LTE) things don’t look good. Verizon may want Apple, but Apple certainly doesn’t want Verizon and they are better for it.
