After upgrading to 3.0, I haven't been able to log into iTunes to download application updates or applications through the iPhone. It keeps giving me the error that the password I entered was incorrect. When trying to use iforgot to reset it, it tells me my ID doesn't exist. I can log into iTunes fine on my mac. The funny thing is that when I plug my iPhone into my mac and log into iTunes on my iPhone when it is plugged in, it will work! But upon unplugging it, it goes back to not working on the iPhone. On a second note, I use my aol account for iTunes. I can log into iTunes on my iPhone fine with my apple ID, but that account is not used for purchasing things on iTunes. Any ideas? Help would be greatly appreciated.
