Two recent studies indicate that in North America and the UK about 40 percent of mobile users are planning to switch to the iPhone 5.
The survey conducted by InMobi, shows that in Canada, US and Mexico 41 percent of mobile phone users plan to buy the iPhone 5, half of them will not wait more than 6 months to make their purchase.
However, this interest will significantly lower if Apple announces just a minor upgrade (as happened two years ago with the launch of the iPhone 3GS). If this does turn out to be the case, not more than 11 percent of clients will remain interested in a possible iPhone 4S/4GS.
BlackBerry users are, according to the study, the most enthusiastic new customers. 52 percent of them will make the switch to the iPhone 5, but only 28 percent would buy an iPhone 4S if that model hits the shelves . Even if owners of Android devices seem more loyal, 27 percent of them plan to switch sides when the iPhone 5 is comes to the market, but only 11 percent are interested in an iPhone 4S.
On the other side of the Atlantic, 39 percent of UK mobile users are waiting to buy the iPhone 5, 48 percent of them in the first six months after the launch. The migration in the UK is at the expense of BlackBerry (45 percent) and Android smartphones (24 percent) as well as 62 percent of iPad users who are planning to buy an iPhone 5.
The release of Apple's star device is to be announced on 4th October and customers could have it in their hands two weeks later, analysts say.
