Here's what i've found out so far... for no reason people are having problems signing in to youtube after linking there google and youtube accounts. i've been trying for weeks and getting quite stressed about it as i've had my account for 5 years with loads of uploads, fav's and messages and so on. luckily i was still signed in on my n900's browser but any other computer, cutetube or other phone app's wouldn't let me in. What you have to do is go into manage account and unlink the google account under manage accounts and bingo! I can sign in on cutetube again and my other android phone. BUT if i try to sign in on a pc it won't let me sign in unless i link the 2 accounts again?? How friggin stupid is that?? So i don't have an answer really but it may at least get some of you using cutetube again propperly. ? And yes... if your not remembered on any computer to manage your account int first place then foook knows what you do?
