YouTube problems on iPhone and PSN?

Ok so 2 days ago I noticed that on my Playstation 3 the YouTube app no longer showed my recent subscription videos OR any of my subscriptions but I can still watch videos if I search for them. On my iPhone 4 however it just says "Tap to retry" as soon as you open it and it never searches or loads a video. Any tops/advice? Or is this just YouTubes problem?

First of all, youtube on psn was updated recently updated so you may have been signed out or signed in but it could of wiped your data of it. About you iphone, i had this problem aswell, i could not get in app store either but the internet worked so it turned out to be that the date/year on my phone was wrong, so go and check it. Hope i helped.
