In fact the Apple/AT&T partnership is going so well that AT&T managed to wrangle another year of exclusivity out of Apple, extending its US monopoly on the iPhone at least until 2010. This extension is part of the iPhone 3G deal that eliminated revenue sharing with Apple, but has AT&T paying about $300 per phone up front. The numbers continue to look good for both parties, with the iPhone generating almost twice the revenue as the average AT&T wireless customer. Then again, it's hardly a surprise. It's not like betting on Steve Jobs' tech business savvy is that much a risk these last few years.
