Iphone Photos - First attempt

I found myself in Birmingham New Street train station today, so I thought I would have a go at taking photos with my iPhone.  What I found was that you had to be really close to people in order to get a good exposure as the shutter speed and focal length can't cope with moving people.  I did get some interesting shots, but overall I was disappointed with the results.  The clarity isn't there and there is too much motion blur.  I couldn't find a way to manually manipulate the iPhone camera settings.
