The following video was shot on my TyTN and submitted directly via e-mail to my YouTube Mobile address:
They sent me back the URL in a few minutes, and I'm now submitting this blog entry through Blogsot Mobile. So the full blog entry, text and video, is done fully on my TyTN, all via e-mail! Nice.
The only drawback is that I expect the YouTube video above will be a link, not an embedded video. (If you read this and see the video embedded in the blog message, it will have worked even better than expected.)
