Blackberry/Nokia cross platform App for Joomla

I need a java application I need a fresh J2me mobile messenger that interacts with Joomla Jomsocial the same way the reference app (the mentioned blackberry app) does. The j2me app should have the same features (+ the modifications and addons). It should be J2me and cross platform (j2me apps can run on nokia phones, blackberry, etc). Can be install on all mobile phones that support java applications like the 2go mobile messenger. ([login to view URL]) Let me have your quotation for this!
