Building on my earlier Balsamiq prototype here's another version of the HyperLocalNews app using the JustInMind framework. This gives a much higher fidelity prototype which to the untrained eye might look more like the real thing. The danger here is that a client might think you've already built the entire app :-)

Note that this is different from the Balsamiq exported PDF in that it's all HTML, and there's no accidental scrolling up and down. Getting a good look and feel of course relies on one knowing where to position things as they would appear on the appropriate smartphone.
