Just wondering if anyone knows when the US can expect GPS receivers based on the SiRF Star III technology. These chips are supposed to be hypersensitive to GPS satellites and should really improve GPS mapping, etc. These are suppose to be able to read signals even inside buildings, etc. I hear they have hit the market in Europe and should be hitting the US market sometime soon. Does anyone know how soon? I'd would like to be able to get reliable GPS mapping on my treo, but if I have to wait another 6 months for a truly good GPS bluetooth it will be a real pain.
