While Apple's iPhone is still one of the most reassuringly expensive toys on the market, it appears that Jobs' Mob has failed to catch on amongst those who can actually afford it. It seems that the very rich have something in common with London rioters - they prefer Blackberries and do not buy iPhones.

According to Prosper Mobile Insights, which recently released its “Simultaneously Media Usage Survey,” if you look around the boardrooms, or amongst those who actually run the world, the iPhone is surprisingly absent. All you will see is Blackberry and Android phones. The survey showed that Blackberry was on top for households with incomes $150,000 and up with only around one in ten partaking of the the Apple Kool Aid.

Among the wealthiest group of smartphone owners, 11.3 per cent have BlackBerry, 10.9 per cent own iPhones and 7.2 per cent have Android smartphones. When the salaries drop to $100,000 to $149,000, 21.2 per cent use Blackberry and 19.1 have iPhones and 15.8 per cent have Android.

What it appears is that as you go down the the upper middle-income levels, iPhone use starts to pick up. In the upper-middle income group of $75,000 to $99,000. About 20 per cent in this category prefer the iPhone, topping Blackberry users at 18.7 per cent. However things flip again in the middle income group whose household income ranges from $35,000 to $49,000 were Android becomes king again.

The survey indicates that one of the reasons that the Blackberry doing better than iPhone amongst business users is its multitasking ability. Steve Jobs decided that users did not want multi-tasking and requires his users to do only one thing at a time.
