Steve Jobs will be holding court once more with a keynote address at Apple's Worldwide Developer Conference tomorrow, and there should be big news on the iPhone front. A new model of the iPhone is expected, possibly with built-in GPS and video iChat capabilities. A software upgrade for existing iPhone models should be forthcoming, as well. Beyond that, who knows what surprises might be coming from Cupertino? Certainly the tech industry will be tuning in to see what the next "must have" Apple products will be.
