This video is quite cool and I naturally blasted a few beauties up onto the YouTuberoo. However, while it does not seem intuitive to turn you camera while shooting video, it's the only way to get a standard horizontal ratio. Otherwise you will get 'phone ratio':

But dig it – the mapping soars with the revised compass integration. I must say putting the mapping with "Trapster" is pretty damn tight. Not that I'm advocating breaking the law.

These features work across multiple devices you configure for push messaging."
