Just link your YouTube account to Facebook. Once you do that, anytime you upload to YouTube from your iPhone, it will automatically send it to your Facebook account.
When I do this facebook won't show a preview of the video like it would if I pasted a link on a computer. I guess people will have to trust my video tastes, unless there's a way for me to post videos with the preview
Btw while I'm home I really haven't used my computer since I picked up the i4
