Ok, got it working. If you want the google maps update do this in terminal
su
mountsys
rm system/app/Maps.apk
cd system/bin
sh pm uninstall com.google.android.apps.maps
unmountsys
Then download the undated maps from the market and your good to go.
Ok, I've tired this many times on a couple versions on Froyo and when I get to 3rd line "aka: rm" I get this
rm:cannot remove system/app/maps.apk:no suck file or directory
Um isn't it installed since it is working? But I can't update? I'm so confused
