For those of you interested in having a messenger for your cell, I downloaded an application called MiM done in java with witch you can access your MSN and Yahoo! Messenger contacts.
It seems that is in a promotional period and its download is completly free, without need of sending any SMS or similar traps, not like other "called free applications". You can download it using your cell internet navigator going to
