Mobile
From textopia
The mobile edition of textopia allows you to walk through the city and hear the texts as you walk through the places they talk about. This requires a compatible cell phone with GPS. For the current version, that needs to be one of Nokia's GPS cell phones, such as the N95, N96, 6110 Navigator, E71 or similar models. (The program has been tested on those four models - most likely it should run on any GPS cell phone from Nokia.)
The new version of the program, currently in development, will run on Google's Android system, such as the G1/HTC Dream.
To download and install the program on your Nokia phone, point the phone's browser to http://textopia.org/m and follow the instructions. If you have problems downloading the program directly to your phone, you can also download the installation files here, transfer them to your phone with a usb cable or bluetooth, and open the '.jad' file to install:
