Okay, So you know how when you subscribe to someone now on YouTube you get subscribed not only to their videos, but to they activity stream as well (i.e. all their favorited videos, etc.)? Well the iPhone YouTube app seems to have trouble with that. On the subscriptions tab, instead of showing all of my subscriptions, and being able to click in them to see all their videos, it's like empty. It's not physically empty, but there are no pictures, it's just a grey box. When you click on their names, it shows you some weird recent activity, and no videos. And on the bottom of that page, it says "Subscribed to 'null'". Is this an iPhone problem? Does anyone else have this with their YouTube account on their iPhone? Remember though, this is only the case for subscriptions to activity streams as well... Also, why does the iPhone app only show you your first 20 subscribers or so? Why doesn't it show you all? Does everyone have that as well? Thanks!
