Apple saw iPhones sales rise 123% year-on-year to 3.79m units on the back of broader availability worldwide, and this contributed to a leap in net profits by 15% to $1.21bn, from $1.05bn a year earlier. Total revenues were up 9% to $8.16bn from $7.51bn though it is hard to judge how much of that came from iPhones, as Apple reports these on a 'subscription-based' model, spread over the device's lifecycle of 24 months. Analysts estimate about $1.5bn, with a margin (also undisclosed by Apple) that is higher than its other hardware products." Via rethinkwireless.com .
