iPhone 3GS drops to $99, 8GB only -- iPhone 3G discontinued

We've already seen the iPhone 3GS drop to under a $100 at Walmart, and Apple has now expectedly made that the official price point following the announcement of the iPhone 4. What's more, the 3GS will now only be available in an 8GB version (it's still not clear if both colors will be available or not), and that naturally also means that the iPhone 3G is now officially discontinued. Of course, there's also still quite a few of the current iPhone 3GS models floating around out there, and AT&T will be doing its best to clear those out -- you can now grab a 16GB 3GS for $149, and a 32GB 3GS for $199 on a two-year plan "while supplies last."
