Hmm I find it easier to use JoikuSpot on S60 + iPod touch or laptop or NIT than imagining to use the NIT as WiFi AP for the iPod touch or laptop while using BlueTooth DUN with the S60 + NIT. OTOH, JoikuSpot eats battery life on the S60. But so does BlueTooth DUN. With JoikuSpot you have one less potential point of failure though. I think I use BlueTooth DUN when possible, and else enable JoikuSpot (full license costs 15 EUR or sth).
