Just bought a 16gb iPod touch 12 hours ago, and it is connected to wifi, internet works, I can download apps. But I go to register my yahoo email account, it tells me I have the wrong password evertime. I had my wife try her yahoo account on my phone and it didn't work either....Not sure what to do? Also, youtube won't come up because it says I need adobe or something like that. Videos won't play.. Any ideas??? thanks!
