My understanding is that CDMA systems cannot reliably use triangulation to locate the handset, at least not within the accuracy parameters required by E911 in the US, so CDMA handset manufacturers use some kind of GPS receiver, probably old technology with newer, smaller, parts, that can then send your location back to the system. Primary purpose for this, of course, is so that emergency services can locate you when you call 911 from your cellphone. Some cellular providers (ie, Verizon Wireless) have developed new services they can sell you that makes use of the location data. OTOH, GSM systems apparently +can+ use triangulation to locate the handset within a reasonably accurate area, and therefore do not need a built-in GPS locator for this purpose. This is probably why the OP thought that the 700p would have a GPS built-in. When I was with Verizon, my Kyocera 7135 PalmOS smartphone had one, as does my dad's Motorola cellphone. As for Telenav requiring a BT GPS receiver, that may not have anything to do with this at all. Depending on the handset and the service provider it was purchased through, some phone features may not even be user-accessible. Forex, Verizon habitually disables things that would make life simple for their users in order to "force" you to pay them for the "service" of allowing you access to your own stuff, such as transferring pictures and ringtones between the handset and your computer. It may be harder for them to do that with a smartphone than with a more "normal" phone, but I'm sure they're trying! -- Jeffrey Kaplan www.gordol.org The from userid is killfiled Send personal mail to gordol "So long as we have enough people in this country willing to fight for their rights, we'll be called a democracy." - Roger Baldwin
