Apple has launched a new online tool to allow potential iPhone 3GS customers to check on the stock levels at any of the company’s U.S.-based retail stores. Currently, iPhone 3GS availability varies wildly from store-to-store, with some stores sold completely out and some down to just one model available; most of the company’s biggest stores, such as The Grove in LA, the downtown San Francisco store, and the company’s glass cube 5th avenue store in New York City, have all models available. The availability checker page notes that the 8GB iPhone 3G is in-stock at all Apple Retail locations.
