3-Lib has ported over the old Psion favourite Mapper/GB to the Nokia 9210/9500 Communicators. With over 1000 towns, 1000 road segments and 8,000 overlay items, plus numerous mapping and GIS functions, you'll be surprised to learn that it's only 300K in size. Version 7.2 beta is at http://3lib.ukonline.co.uk/mapper.htm
