iPhone 5 / 4S placeholders pop up at Cincinnati Bell, questionable specs in tow

It looks like the iPhone speculation train is gaining steam on the way to its final destination, and this time it's flying by Cincinnati Bell's pre-paid service, i-Wireless. A helpful tipster sent in the above screenshot of an iPhone 5 placeholder, accompanied by a $639.99 price tag and a handful of specs: 32GB, 4-inch screen and 4G data speeds. Our friends over at TUAW have also procured a screenshot (after the break) from the same site, displaying a $99.99 16GB iPhone 4S, sporting a 5MP camera, 3.5-inch screen and an A5 processor. Of course, there's also a chance these are just placeholders, but we're hoping Tuesday's announcement will bear dual fruits, nonetheless.
