Doesn't work for me. When I try to get on TB a white page comes up and says "Something has gone wrong. We've run into a problem and are unable to handle this request right now. Please check back in a little while." And theres a face with X's for eyes in the background.

From iphone: Click the open book icon at the bottom. HISTORY should be the first or second option. Click that and the hit "clear" on the bottom. :]
