Step1: Install TCPMP 0.72RC1. To do this run Pocket Internet Explorer on your phone and type this url: http://tinyurl.com/wafj8. When prompted to download click Yes. When prompted to install click "Install". At the end of the install it will give you a message about the program being made for an older version of WM. Don't be alarmed, it will work fine.

Step2: Install the YouTube plugins for TCPMP and Pocket IE version 1.1. To do this just run Pocket Internet Explorer on your phone and type this url: http://tinyurl.com/36ntkl. Answer all the prompts the same way you did in Step1.

Step3: Reset the phone by pulling the battery and then plugging it back in.
