I know there has been many questions and complaints about watching youtube on our blackberrys with TELUS and they have just opened up streaming not online for youtube but for any streaming website and you don't even need OS 4.5 to do it! Even if you're running the stock 4.3 OS you can stream videos in your media player! If you don't believe me try it out just go to m.youtube.com on your blackberry and try watching a video! This discovery made me so happy that i decided to share my news with the rest of the community. Enjoy!
