All you need to do is take a few things we're already doing, and put them together to discover how they'll converge.
Twitter: the updating service that sends what you're doing to anyone who cares to know, wherever they happen to be, via their phones.
Flock, the browser that sucks information from all of your contacts on Facebook, Youtube, Flickr and Twitter and feeds them to you in a single constantly-updated stream.
And the iPhone, the phone that presents photos and videos in a quality far more advanced than any other phone on the market.
Combine these three technologies and what have you got? It's not too difficult to imagine, in the next year or so, a mobile version of Flock where your phone will be constantly lighting up with all sorts of information from your friends and contacts. Status updates, new photos they've posted, new videos they've uploaded, information as to their location... your phone screen will be a constant feed of information.
We already have pushmail, where emails arrive in your inbox without you needing to do anything. It's only a small leap from that to push-updates, with all new information in whatever form posted by your contacts appearing instantly on your iPhone screen.
