Not quite. The PDA must itself have a USB port in order to sync via USB.
To sync via standard RS-232 (serial), again it must itself have a serial port.

The cradle is usually just a fancy plug for the bottom of the PDA.
In some cases the cradle will have level shifting hardware for the RS-232 interface.

While there might be exceptions, this is generally the rule.
