Metro iPhone app alternatif

If you don't own an iPhone (or better said if you're not owned by an iPhone) and hence don't have the handy iPhone application from our last post, you can use the online interactive metro-map. (you can use it on any mobile device that lets you brows websites)
Mark the starting station and your end point and the site gives you the best way to go with the time it will take, the cost etc.
It's very complete and easy to use. Only drawback is that it's in French only at least i was not able to find a menu where you can change the language.
The main information site of RATP comes in several languages.
