Since the leaked prototype that ended up in the hands of tech blog Gizmodo is obviously very real, we don't expect too many surprises. We expect the iPhone 4G (as it will likely be called) to feature a front camera, an upgraded back camera, improved display, microSIM support and metal details on the case. We don't doubt, however, that a wave of rumors will precede the official announcements; after all, we're talking about Apple, one of the most secretive companies in the world. You never know what it might have up its sleeve.
