Using the browser on the LG 800G I went to maps.google.com and saw a line saying "download google maps" or such. I took that. then it said showed a screen saying something like "use this link to download" so I took this link but it said I was downloading an unsigned version, so I cancelled and clicked this link again, and again it said I was downloading an unsigned version.

I kept cancelling until it gave me a signed version. I felt dumb and I wasted some minutes but I got the signed version!
