yeah.. finally!! my GPS can work already..
I was tried this method:
1. Turn Off GPS
2. Open LibTestMode. If you do not know how to open it then you can open it by typing the following code in the dialer (Froyo Only): *#*#3214789650#*#*
3. Under "Application settings" Change "Operation Mode" to Standalone. (Some people have reported better accuracy with MS Mode)
4. Under "Application Settings", Change "Timeout(s)" to 100
5. Under "SUPL/CP Settings" Change the SERVER & PORT to supl.google.com and port 7276
6. Reboot

afterward i tried method 1, which post on 1st page, and try at outdoor, it can find 9~10 satellite and PAPAGO can detect where m i already..
