SavaJe, a spinoff of Lucent Technologies, threw its hat–or, rather, cellphone–into the ring at the 2006 JavaOne Conference in San Francisco this week, with the unveiling of a “sophisticated” handset that runs a unique, Java-centric operating system. The Jasper S20 mobile phone, made by Group Sense Limited PDA and running SavaJe’s Java-based SavaJe Mobile Platform, also garnered JavaOne’s “Device of the Show” honors.
