Motorola V400

I've been doing a lot of research on this phone. I have had lots of time to fiddle with it, as well as the Nok 3600. While I want to purchase the Mot V400, I have found that the 3600 has an AWESOME (super freakin' awesome, ctually) set up of Applications, where as the v400 lacks in that department. I am pretty sure that both phones run off Java, so is it possible, with the aid of data cables, to copy them over? Or even write my own programs, and add them via data link? Any feedback would be much appreciated.
