I am getting this error on the G1 (so the advice to "-wipe-data" is
not possible) and need help getting around it.

   Failure [INSTALL_FAILED_UPDATE_INCOMPATIBLE]

   Package com.frogdesign.test1 signatures do not match the previously
installed version; ignoring
   Package couldn't be installed in /data/app/com.frogdesign.test1.apk

I have a few apps with a 'shared user id' - I installed two apps that
use the same shared user id and the two apps were built on different
machines so I realize that is the source of the problem.

However, I am stuck!  I uninstalled (via "adb uninstall <package
name>") all of my apps and tried to re-install a new build (suite of
apps) which was completely built on the same machine.  It appears that
the system is keeping around some old data (maybe in the cache?) for
the apps that I uninstalled because I get that error when I try to
install the fresh apps.

If anyone can please help I would really appreciate it, it's
completely blocking us from testing our apps on the G1.

Thanks,
Cheryl
