The next-generation iPhone is coming soon and one of the big rumors is that the phone will include legitimate GPS and not the half-assed location-based GPS like the current generation. That has some other GPS manufacturers shaking in their boots. One unnamed president of a GPS manufacturer said the prospect of the iPhone with real GPS has him "scared shitless." We're not too surprised by this notion, either. With windshield suction mounts available, there wouldn't be a reason to drop a few hundred on a top-of-the-line GPS navigation unit when your mobile phone can accomplish the same job.
