I am using this Setting in SULP (Secure User Plane Client With Extended Ephemeris)

[HKEY_LOCAL_MACHINE\Software\HTC\SUPL AGPS]
"GPSMode"=dword:00000001
"EnableGPSSmartMode"=dword:00000000
"EnableAGPS"=dword:00000000

GPSMode = 1 means Autonomous (Self Fix no Assistance Required, Pessimistic Approach, Very Slow but Very Accurate)
GPSMode = 2 means Assisted by Server (Less Optimistic, Somewhat Slow but Medium Accuracy Quality)
GPSMode = 4 means Assisted by Server with Extended Ephemeris (Very Optimistic, But Sometime we loose Accuracy Quality)

EnableAGPS = 1 Means Enabled AGPS and 0 Disables it

EnableGPSSmartMode = 1 Save Downloaded Ephemeris Data and also Send it Assitance Server to Update / Fine Tune Extended Ephemeris Data on Server (Require Internet Connection), 0 Zero Desables this Feature

Ephemeris Data = To get Self Fix the Device must know the Position of Satelite in sky, which is called as Ephemeris Data, This is Combined Database which have there Altitude, Latitude, Longitude so the Phone , GPS Device don't have to wait to get Satellites Position from Frequent Satellite Self Position Broadcast by Air

Do you use anything to prime the GPS? I use Quick GPS, which downloads the SAT location info from the Internet to my 6800, and should help speed locks up...but I say should because it does not always work. I was in a cab in NYC on Thursday, and the cab had a SAT lock but I didnt for over 15 mins. Was very frustrating.

I am actually going to change the setting of Smartmode to 1 since I have an unlimited data plan...yea! Next you talk about a SULP client. Where can we obtain this?

Any assistance from you would be ideal. I love to learn.
