I just want everyone to know that twitter bought a company and liberated an
app that allows the user to send encrypted text messages. This is great
because texts are not encrypted by default. This protects them from being
snooped on while they are on the wire. It also encrypts them locally on your
phone so if you lose your phone or it is seized by someone like a police
officer they won't be able to read them (contact a lawyer in this situation).
Even better it is released under the GPLv3 which protects the user and their
freedoms!!! It is available through f-droid
(http://f-droid.org/repository/browse/?fdid=org.thoughtcrime.securesms&fdpage=5)
which is a free alternative to the android marketplace and has only free
(libre) software in it.
I would recommend that anyone running an Android/Linux (or derivative such as
replicant) replace the default text messaging app with this free (and
actually enhanced) replacement.
