Yes for anyone who isn't DarthEnder, I would recommend the manga, its leaps and bounds better than the anime even if its for the simple fact that flashbacks usually take no more than one page or a few panels and there is the bonus of never having to hear Naruto's voice. Plus you don't have to deal with all the filler stuff they inject into every episode basically besides the built in stuff like Naruto's stupidity and Sakura's lack of battle skills everything else you guys complain about is gone.
Anyway to get back on topic, to the people who ask what Jiraiya has been doing with Naruto all these years the answer is simple. As we've seen before Naruto is not easy to teach and since everyone agrees that he is a no talent hack all Jiraiya has been interested in was teaching him how to use more of the Kyuubi, which is probably the most significant reason why Naruto can now go four tails.
From Jiraiya's previous attempts at teaching Naruto (summoning+rasengan) its obvious that Jiraiya doesn't have much patience for teaching him actual techniques although he did teach him to use Odama rasengan. Anyway my point is that Jiraiya is interested in teaching Naruto to use and control the Kyuubi, which at this point is not only Naruto's greatest asset but seemingly his only one, interesting that Sasuke completely negates that. Its not like Jiraiya can't teach because there is that other yellow haired student of his.
