The iOS interface is based upon direct manipulation , using multi-touch gestures. Granted, I wasn’t knee deep in the Amazon rain forest, for which this whole WiFi scenario would have been moot, however the Caribbean and Atlantic islands are immersed in intermittent WiFi – the grade of which is not equal unfortunately, but it affords a few free avenues of communication if you have a good phone – and one particularly brilliant and flawless avenue if you provide an iPhone.
