Apple has been prepping the Yerba Buena Center in San Francisco for Wednesday's big event, and anticipation is building to a frenzy. By now, few surprises are expected, since so many details of the forthcoming iPhone 5 have been leaked. The consensus is that it will be taller, with a 4-inch screen, and will have the same width as previous iPhones. It will likely have LTE 4G data speeds. And there will be a new 9-pin dock connector.
