Firstly, apologies if this has been posted before, I did check, but could not see a posting. I have recently come across "MetrO", free software for smartphones and PDA's, which has maps of every metro / underground system in the world, including Prague. Basically, you enter your starting point and then destination, and in the case of Prague, the software tells you the metro line, tran number or bus number you need, together with any changes, the number of stops you must travel, and the expected journey time. MetrO is available here : www.nanika.net/metro WAP and webpage versions are also available to those without PDA's / Smartphones
