Also, just food for thought: "When taken together, autonomous civilian GPS horizontal position fixes are typically accurate to about 15 meters (50 ft). These effects also reduce the more precise P(Y) code's accuracy" I pulled that from Wikipedia. The "My Location" which triangulates, will actually TELL you how many meters its off. In my home for example, my roommate's BJ II and Blackberry tell him "My Location" is accurate to within 3 meters. The VERY conservative number they give in literature and their video is because they are accounting for worse scenarios, which some might have in less coverage areas. The more cell towers, the better your chances of increased accuracy. Also, they mention in their video, the more you use the feature, the more accurate it becomes. THATS really what is intriguing me about the technology, and why I want to get it work, if even only partially.
