Quantities likely extremely low
Some RadioShack outlets may still be stocking the 16GB version of the iPhone 4, a new training document suggests. The document states that both 8 and 16GB models are available for $100 with a two year contract, and that the offer is "good for AT&T, Sprint, and Verizon." No 16GB iPhone was ever built for Sprint however; only the 8GB option is available with that carrier.
A warning in the document cautions that the 16GB model "may not be in great supply." Apple officially discontinued the product when it announced the iPhone 4S, but many 16GB iPhone 4s were left in circulation for carriers and other vendors to clear out. At this point, though, companies would have had about three months to sell old 16GB phones.
