On the iPhone at least. Android and other smartphone platforms have had livestreaming video apps for a while now. But the tide has finally turned in the favor of iPhone users too – as Ustream has finally had its app approved for distribution in iTunes (app store link).

For me, this release culminates three of the biggest technological trends of 2009; Lifestreaming, Location, and Video.

First up – Lifestreaming. Twitter. Facebook. You’ve probably heard of these sites. It’s now easier than ever to instantly share events to a large distributed audience online – what you’re doing. By sharing information via these networks you are building connections and, by extension, reach.

Location. GPS is nearly omniprescent in most modern smartphones. Your devices now know in an instant where you are in the world. Apps like Google Latitude, Foursquare and my new fav – Gowalla, all exist because they know where you are. So too do augmented reality apps like Layar (see Layar Technology Now Available for iPhone). Location awareness is a true technological paradigm shift.

And finally video. I’ve been on this soapbox long enough. But the web is rapidly becoming about video and video content — witness Comcast’s bid to acquire NBC/Universal; a traditional “pipe” getting into the video content game. Or U2’s massive live concert on Youtube that generated over 10 million streams across 7 continents.

So what does all this mean? The Ustream app has magnificent repercussions for citizen journalism, family ties and yes, even real estate (think of working with a relo client remotely to show them properties, for example). The power to broadcast live, each of us from the palms of our hands, will certainly change the way some of us communicate.

Time to go fire up my phone.

You’ll be able to find me here. Live.
