Well at last I can download open street maps to use offline with my android phone!
There is an app called Locus maps this allows you to view online maps ,and now download them as well.
when downloading I would sugest selecting zoom levels 1 upto 23 as level 24 takes 4 times as much memory and you dont really need it.
You can also put gpx files into the locus directory on your phone and they are displayed on the map.
Locus can display cache details , description and logs without the need for another geocaching app on your phone.
If you use G:geo any list (nearest caches , stored caches etc) can be displayed on external map ( press menu display on externay map then pick locus)
Once a map is saved on your phone it can be copied off of the sd card onto your pc and shared it takes a while for ech map to be created by your phone so sharing is good.
There is a program to run on a pc for making maps to be displayed on Locus instead of doing it on your phone but I have not tested that yet, it's called
Mobile Atlas Creator
