Refurbished iPhones available from AT&T -- Sold out
UPDATE: AT&T's online stock of refurbished iPhones is now sold out. The listings no longer appear.
If you're still looking to pick up a current-generation iPhone and haven't found stock at local Apple or AT&T stores, AT&T's Web site is now offering refurbished models at a fairly deep discount: $250 for the 8GB edition and $350 for the 16GB edition. Purchases are limited to "one per customer and per household." AppleCare protection is available for $70.
