Offline maps on your droid....
As good as Google Maps is on Android (and it is good!), you have to have a data connection. Whilst it can cache some data (and it looks like there are some workarounds to increasing this) it don't store the entire UK!! So I had a quick look around for something that does do offline storage... and there seem to be a few rambling apps that use OS data (and some online ones as well). I started hunting around for Open Street Map products and MapDroyd popped up as one. You can download street level OSM maps for wherever there is coverage and store it on your SD card. The entire UK comes in at about 180Mb which is pretty good. I'm non-too-happy with the styling but it works and is OK. There is no routing (coming in the paid-for app) and you can't overlay tracklogs, but you do get the entire world on a streetmap and you GPS position places over it. Worth a play with.
