Couple questions from first time symbian user :)

So, first of all - hello all Nokia N8 users! Now i have a couple questions. I'm first time symbian user, so there is things i don't know. Like - do previous symbian versions games works on symbian^3? Like, there is a game i want install, its from S60v3 version, can it work on symbian^3? And other question - where to install games, like that particular game has folder, in witch there are .sisx file, and game data folders. So how you install this game? Just copy .sisx file and run it, and then copy game data to E:/mass memory/games? And thats all? And final question - that game requires PIPS. Does this symbian version automatically have it? So there is couple questions, i would be thankfull if someone answered them

RE the question of S60v3 : I think games have to be S60V5 or after as V5 [symbian^1] was the first to support Touch-screen and thus V3 games expect a keyboard?
