“iPhone-Myopia” - a treatable condition where individuals see iPhone as the only major mobile platform.
 
When I discuss mobile app projects with clients one of the first questions I ask is: What platforms are you thinking of targeting?  iPhone, Android, iPad, Blackberry, or Windows Phone 7?  Often the response I get is: “only iPhone”, “Our customer’s only use iPhone”.  Unfortunately the most likely scenario is their customers use many devices beyond just iPhone.  Developing a mobile strategy for one platform may or may not be an affective approach.  Currently the iPhone represents only 27% of the smartphone market which is 3rd to Blackberry and Android.  Additionally in the United States Android is now the most-used smartphone operating system with 31.2% market share that is continuing to grow.  Why is this?  Android operates on many devices and has exposure to most major carriers beyond just Verizon and AT&T. Android passes BlackBerry
 
Also don’t forget about Blackberry and Windows Phone 7.  Each have their own issues but I wouldn’t exclude them from your strategy.   With the release of Blackberry OS 6.0 and the Torch, Jam-Mobile’s Blackberry app sales have been UP over the last few months.  Lastly Windows Phone 7 Platform has a small market share but it’s backed by tech giant Microsoft.
 
Should you start your mobile strategy with iPhone?  Yes.  Should you consider other platforms like Android, Blackberry, etc?  Only if you want to reach a majority of the market and touch the fastest growing platform Android!
