I know, you've heard it many, many times before. But those whispers of an iPhone mini just refuse to go away. In fact, they're back with a vengeance, with Strategy Analytics' Neil Mawston claiming a mini iPhone will land in 2014, purely to bump up the company's market share."We believe Apple will have to launch an 'iPhone Mini' at some point over the next three years to address the hundreds of millions of prepaid users worldwide that cannot afford the current iPhone," Mawston said. "The iPhone 5 is growing fast and profitably right now, so there is limited incentive for Apple to launch a profit-squeezing iPhone mini this year."He continued: "We expect the iPhone mini' to be more likely next year, in 2014, when Apple's penetration of the global postpaid smartphone market will be nearing saturation and Apple will be forced to discover fresh growth streams elsewhere."Mawston probably has a point. Apple could hit saturation point for users, which in turn limits the market for its apps and media. A smaller and cheaper iPhone would deal with that problem and fight the likes of Samsung on other fronts - Samsung's total share of global smartphone sales is currently 31 per cent, compared to Apple's 21 per cent. That's pretty much down to Samsung having a wider spread of phones.It isn't the next Apple phone though. That's likely to be the iPhone 6.
