I want to buy an ipod touch, but have some questions. Does it have bluetooth? Is there anyway to get some sort of GPS without wifi? How hard is it to jailbreak one? Can you play nes games and what other fun games can you get? How do you use the controls? Am I correct in saying that there isn't any speakers you have to use headphones? Also one more, I think I saw an app where you can make VOIP calls with the ipod touch, anyone use this? Thanks.
