Great work!

Would you mind adding your notes to https://wiki.ubuntu.com/Touch/PortingFlippedInProgress? It'd be great if we could collect information collectively and update the guide to the new world order together. :-) Have a great day, Daniel -- Get involved in Ubuntu development! developer.ubuntu.com/packaging Follow @ubuntudev on identi.ca/twitter.com/facebook.com/G+ -- Mailing list: https://launchpad.net/~ubuntu-phone Post to : ubuntu-phone@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-phone More help : https://help.launchpad.net/ListHelp
