9530 on MetroPCS fully functioning

With the exception of a couple apps, youtube and ymessenger. Its version 5.0.0.328. I'm new to this and got my bb a couple of days ago. I bought it unlocked/flashed already but it was a little tricky getting it connected. My biggest problem is the youtube not working... I LOVE YOUTUBE and honestly, the web works beautifully faster than I thought. I live in miami if that makes a difference. When I got it the person said I'd be able to save the youtube vids and view them that way. Well it takes me to the main page but doesnt play the vid ( like a comp would ) and when i click it an error pops up. Is this possible. It lets me d/l bolt browser but when i go to open it says ERROR INTERNET NOT AVAILABLE. CHECK NETWORK SERVICES. Guess i shouldn't be complaining so much but I was really expecting youtube. So if anyone can give me some insight that would be greatly appreciated. Thanks In Advance.
