This story is false. No one would post such a story without a video that is stored on a mobile phone. OP would be more credible had not mentioned the existence of the video.
Connect the video to the computer with the cable. Get the video off the phone to the computer. Look at the extension of video size. Go to google and type
" .EXTENSION to .avi converter"
Where instead of EXTENSION, you type the extension of the video file, probably 3gp or mpg or something else. If it already is .avi you dont need to converte it. Just post it straight on youtube.
If the extension is something different download that converter. Its probably a free trial, convert it to .avi and post it on youtube.
But i think youtube supports other file types then .avi, so you should first try even if its any extension.
