Ummm . . . I thought the cell phone was a radio . . .
A Yugo is a car. A Lamborghini is a car. A Jeep is a car. BUT they are not equivalent and to pretend otherwise is poking the bear.
In this same way a cell phone is a versatile tool but it is not point to point, it is short range and dependent on a complicated and fragile network that will go down in any serious crisis.
Ham radios are robust, have worldwide reach and although repeaters exist, ham radios do not need ANY network to function reliably.
This makes them the communication method of choice in real emergencies, which is why ARES exists.
Here is a useful list that was provided by Paul Olson after Katrina, but you can find local resources by searching ARES + your state's name:
USB = upper side band
LSB = lower side band
