MGmaps (not Mobile Google Maps, but Mobile Gmaps. a free (as in beer) 3rd party client) does exactly this. One big issue is the filesystem: individual tiles are small but they end up taking tons of space once you put them on a FAT32 SD card.
It's usable but you have to fine tune what zoom levels you store (= get the zoomed in tiles only for dense urban areas).
