I think Mark had posted something about how some java games made for other java-based phones would work on blackberries. Pretty much just gotta try it to see if it works or not.
Basically the games are probably loaded on there as a .jad or .jar file. You can just host the file on a website of your choice, point your BB browser to the location and it should install (if it's compatible).
As far as how to get them off the i95, I've never used/seen one of those so I couldn't be a lot of help there.
