It’s official, AT&T has sold out of the 8GB iPhone 3G. But that’s not as exciting as the clue provided to us by AT&T about its replacement and the iPad’s soon-to-be-dead unlimited plan.

BGR is saying the departing 3G model will be replaced with a $99 3GS soon after the new iPhone is out. And the New York Times is reporting that AT&T has gone ahead allowed customers to just buy – not have in hand – the iPad 3G and retain the right to select the unlimited 3G data plan – for a very limited time.

To be precise, you have until June 6 at 11:59pm to get the iPad on unlimited 3G. Run, you fool!
