Just thought I'd flag up that the latest release of Google Maps (v5.7) now allows users to download maps! It seems a fairly major upgrade as it also allows the planning of journeys using public transport.
To download what Google call an 'area', do a long press at the centre of the area you want to download and then wait for the address to load. Then tap on the address bubble - this will take you to a screen that now includes an extra option "Download map area". Pressing this will download an area of ten miles by ten miles to your phone. You can download multiple area... they can be seen under Menu -> More -> Cache settings -> Downloaded map areas.
