I am expecting (hoping) that iPhone2 will have integrated GPS functionality. However, the Wi-Fi/cell tower locate feature makes me wonder if this is as good as it gets. It's quite impressive for what it is, but I assume that its use outside of urban areas would be less than desirable or even functional at all. But maybe that's the point. Without Wi-Fi or EDGE access to load Google maps, integrated GPS would be useless (?). (Unless, of course, maps are preloaded in some fashion.) Why include a GPS chip if the iPhone won't offer maps everywhere? Does this theory sound reasonable? What am I missing here?
