If you have iPhone, then you have a technology that is even better than A-GPS. It is called Skyhook Wireless technology and it uses the Wi-Fi capabilities of a phone along with its GPS system and cell towers. The ability of Skyhook to glean the position information from 3 different sources makes it more accurate especially in places where satellite signals are weak. Nokia’s Ovi Store and Apple’s app Store both have applications based on Skyhook You can visit http://www.skyhookwireless.com/howitworks/ and http://en.wikipedia.org/wiki/Skyhook_Wireless for more information. The presence of additional technologies on a cell phone makes it even more useful than a stand-alone GPS navigation device. > I > have used nokia maps > with sighted assistance and they give turn by turn > direction announcements > that are just as good as wayfinder. That's true, although Wayfinder's icons were most likely labeled. When you go into Talks Icons settings sheet, you can find direction related graphics labeled like Left turn, Right turn, etc. > Not to mention Google > maps (I am looking > for a product that will give turn by turn announcements > with Google maps). TalkBack with Google Maps does that, but I’m digressing away from the phones under discussion. http://www.youtube.com/watch?v=PQTtpigxpWw Regards "For once you have tasted flight you will walk the earth with your eyes turned skywards, for there you have been and there you will long to return." ~ Leonardo da Vinci To unsubscribe send a message to [email protected] with the subject unsubscribe.
