But wait, there's more.
Apple has published a handy chart comparing the iPhone 3G to the iPhone 3G S. As you might expect, it does not clearly portray some key problems.
Tethering, a feature of iPhone Software Update 3.0, will not be made available in the US. (Thanks AT&T.) If it happens later, it will be after AT&T adds a more expensive data plan.
MMS, another feature of iPhone Software Update 3.0, will also not be made available in the US.
The white iPhone 3G is being discontinued. If you want a white phone, you have to get a 3G S. (Not a huge deal, just pointing it out.)
By the way, was anyone else amused at the sly way Apple "countered" the Palm Pre's useful and easy-to-use multitasking capabilities? In the iPhone 3G S Guided Tour video, the commentator notes, "The first thing you'll notice is how quickly you can launch all your applications, return to the home screen, and then launch another one. Or jump between apps using embedded links." See! It's just like multitasking!
