There have been rumors about a 8GB iPhone 3GS going around since the summer. But a man in Hamburg, Germany who recently bought a refurbished 8GB iPhone 3G was supirsed to find on the label that it said “iPhone 3GS v2.2, 8GB.” The model and part number are for the older model, but “iPhone 3GS” appears on other places on the packaging as well, implying that the label wasn’t just a typo but an actual part label for an existing or soon to be existing iPhone model.
Back in August, screen caps from an internal website for the Canadian iPhone provider, Rogers Wireless were posted to the internet showing a 8GB iPhone 3GS and stores were apparently under strict orders to sell out their current stock of 8GB iPhone 3G to make room for the new 3GS, which never appeared in stores.
