I have just bought am iPod touch. I want to download apps from the 'apps store' I have on my iPod touch. I signed up at apple.com for an iTunes acct but whenever I try to download at the 'apps store' on my iPod touch, and I'm asked to log in, it keeps saying 'authorization failed' pls connect to iTunes. I do not really know what that means. Do I have to connect my iPod to the pc before I can download? Or does that mean I am entering the wrong details that's why authoriization failed? I really want to download apps so pls help me. Also if there are other ways to download and install apps pls let me know as well. Thank you!
