Apple has discontinued the 8 GB iPhone 3G (this was, until its discontinuation, the oldest iPhone sold by Apple, not the iPhone 3GS). The phone is no longer available for order on the Apple website.
This move is not really surprising because Apple is expected to introduce a new iPhone soon. Plus, the company was offering a pretty good discount on the iPhone 3G. Once the new iPhone is out, the iPhone 3GS will probably become discounted as well.
There are other signs that a new iPhone will be arriving shortly: Wal-Mart has lowered the price of the iPhone 3GS to $97 (just as a side note, the idea of Wal-Mart selling iPhones is wrong in so many different ways) and there have been reports that Apple is casting for a new iPhone commercial. Plus, there was that iPhone lost in a bar a little while back.
iPhone 3GS, your days may be limited.
