Using GT-I9000
Android version 2.2
Build : FROYO.BUJP7
Location : Brussels (Europe)
Couldn't get GPS locking in a stable way.
Have tried in LbsTestMode :
Operation Mode : both "standalone" and "MS Based"
Server : supl.google.com port 7276 ; also tried :
www.spirent-lcs.com port 7275
No luck and no lock

Question 1:
Does the GPS functionality work without a DATA connection/subscription to an ISP ?
(I switched off "Wireless networks" in Settings, prior to each change in LbsTestMode, switched OFF the phone, switched it back on (effectively rebooting), and switched "Wireless Networks" back on)
Question 2:
Can anyone confirm whether LbsTestMode is a core interface between the hardware and all apps using GPS ?
And if so, are there any buggy versions around ? As previously stated, I'm running a stock FROYO.BUJP7.
Additional info:
Using App GPS Test, I obtain sometimes a couple of satellites "In View", but none "In Use".
Settings in LbsTestMode:
Application Settings:
Session type=Tracking
Test Mode=S/W Test
Operation Mode=Standalone
Start Mode=Hot start
GPS Plus=ON
Dynamic Accuracy=ON
Accuracy=50
GPS Logging=OFF
SUPL/CP Settings
Server FQDN Type = Custom Config
Server= supl.google.com
Server port=7276
SUPL Secure Socket=OFF
AGPS Mode=SUPL
(Have also tried several times to Delete GPS Data)
Hope someone experienced the same, and found a solution...
