Paula Chowles of the Wired (you need to take adblocker off for this one) goes through how it's possible to create first class video on an iPhone in her piece "How to Film a Hollywood-Worthy Movie on Your iPhone".

The phone cameras are so good now, that with a stabiliser and decent lightning (basically film with the sun, not against it) – no one will know the difference.

Yours truly has recent first hand experience with this. You know times have changed when nobody is selling miniature versions of famous landmarks by famous landmarks in popular tourist destinations any more.

Added benefit is that it's not just for selfies.

As Chowles mentioned in the article, you could do the moody artistic 'I don't even know the camera is there' (we know someone on our team that has done this with a great result), but also point the stick straight in the air and take photos that don't include the back of other people's heads when in a crowd.
