41% Plan to Buy iPhone 5

Could the iPhone 5 be Apple’s biggest hit yet? Consumers still haven’t even seen the device—it’s set to be unveiled Tuesday—but a recent survey from the mobile ad network inMobi found that a whopping 41% of North American mobile users are already planning to buy the thing, MSNBC reports. And those sales will come at the expense of Apple’s rivals; more than half of BlackBerry users (52%) plan to defect, as do 27% of Android users.

Of course, all those numbers go straight out the window if all Apple unveils next week is a modest iPhone 4 upgrade; less than 15% say they’d line up for that. Click here for the survey. (More iPhone 5 stories.)
