Pablo Oliviera from ENST Paris, France has tested Concierge with PhoneME Advanced MR2 on a Nokia 770 Internet Tablet. You can find instructions on how to build MR2 for the Nokia 770 here or use these binaries.
Because MR1 or MR2 currently do not provide GUI capabilities on the Nokia 770, you won't be able to start the splash_screen bundle. Thus you should comment the following line from the init.xargs file at the root of your concierge distribution:
# -istart splash_screen-[version].jar
Then Concierge can be started with:
cvm -jar concierge-[version].jar
