Just browsed a bit with gconf-editor and what do I see...

Modest saves cleartext password in his config!

Come on, it's not nice to not have a usable PIM (can't send email with GPE addressbook, other PIMs lacks in other points, and so on...) with Nxxx tablet, but storing cleartext passwords on a mobile device isn't acceptable!

PS:
What's also not nice in Modest: at fullscreen, there is no close button in mail view to go back to the listing view.
