If you cannot install any packages after you update modest:


create /etc/apt/preferences and edit like this:

package: libtinymail-camel
pin release: a=unstable
pin-priority: 1000

package: hildon-desktop
pin release: a=unstable
pin-priority: 1001

save the file, reboot if you are unsure (last pin is for http://talk.maemo.org/showthread.php?t=60599 )

I don't guarantee that trick works! Remove the preferences file you want to get rid of hacks. Then do apt-get get upgrade or apt-get --fix-broken install or something like and you should get the old ones back and able to install new apps
