[OTR-users] encryption on mobile phone?

[Michael Reichenbach]

I don`t think it`s needed until any 100% Open Source mobile device is done.

Afaik the most used common platform is java j2me, followed by symbian 
C++, followed by windows mobile.

Are there any Open Source messengers out for any of this well used 
platforms?

Also any Open Source solution which is packing sms / using internet (to 
write longer messages for same money) are interesting for that.
