i'm thinking about buying n800 , there is a solution to youtube but what about java ? online bank and game sites esp. could you trythat online game site for me ? and report me if there is ok or not. thanks..

Java is only a dream. It still does not work (neither for web nor for applications). Maybe in a future. Jalimo team is working on it (I hope so).
Old Jdk1.3 works (jamvm).... but it's too old stuff.
