serial port vs. USB?

The connector, used to upload and download names and numbers, on the few
cell phones I've been able to test, use PC serial port methodology, and
require a wire with electronics to be able to connect to the PC's USB port.
Is this universally true? Are there any USB-only cell phones? I believe
some Sony-Ericsson models use only Bluetooth. TIA for info or pointers to
documentation.

The SonyEricsson Z1010 ha a built in usb port for true usb-to-usb
connectivity.
