hi all, for some reason i can't seem to log in to the built-in youtube app. it works fine via the browser, but when i try to log in via the app it says either "the username or password isn't valid" or "there was a network error while trying to sign in to XXX. retry now or press the back button to cancel". i'm going on vacation in two days and was looking forward to uploading a few movies on the fly. looks like i will have to do it manually via the browser any ideas what's going on?
