640k are enough for everyone, right? ;)

What I'd like to see is an easy way of storing *all* important data
(phonebook, SMS, addresses, pictures, music, you name it) on the microSD
card instead of the internal flash.
Then I can just make one large encrypted 2GB LUKS partition on the microSD
card and everything is encrypted. When the phone is rebooted or the microSD
card is removed, the data is safe until the passphrase is provided.
One remaining question is if the user manually wants to lock the phone
during use (usually with a PIN). We can't really unmount the microSD card
because then the phonebook is unavailable and incoming calls can't tell who
is calling (and how to treat the call). So I guess it remains mounted all
