Servo on any I/O pin?

Using Arduino Motors, Mechanics, Power and CNC

Can I put a servo on pin 1? If so, then I should be able to plug a servo in the FTDI plug on the pro mini, on pins 2,3,& 4, which are GND,+5V, and RX.
thanks

(assuming I won't be using Serial)

You can put a servo on pin 1, but you can't use the normal servo library to drive it. You can use the software servo library (Arduino Playground - HomePage) instead. There are other limitations to using software servo. It isn't 'set and forget' like the normal timer based library, you have to regularly 'refresh' the servos.

So what pins can you use the regular servo library with? I don't see this info on the Servo Page.
