Before to procede, remember all electrial component can have fault so exist warranty. If you want, procede at your own risk loosing warranty

For this tutorial is raccomanded professional leadfree soldering iron

i solved my gps problem, it is hardware problem, so no settings, gpsaids and no other solution helped me.

Problem is caused by bad gnd conductivity between mainboard and antenna. It is conduced by:

1) CONDUCTIVE GUMMY (suggest me better name if you have ) This kind of rubber was used for old nokia 8210 for connect display to mainboard. It was the mayor fault for nokia 8210.

2) back cover gps antenna: When phone become hot, antenna go back and not good touch with motherboard. Then, when phone isn't hot, gps antenna remains with a kind of "hole"


First try software fix (it not helped me) then try my solution

Solution:
Attention: it will avoid warranty, do it at your own risk, i'm not responsable for any fault.





SOLUTION:







here is antenna contact not used for my european i9000
Please check by yourself if it touch with your variant antenna,
if it is not used, you can remove and solder where was rubber








Now gps signal is immediate for me

Best regards
Leeno

i moved in this third post the other solution,
it is easyer then solution in first post but i not like it because is not clean


Attention: it will avoid warranty, do it at your own risk, i'm not responsable for any fault.

For solve it i just removed rubber and soldered antenna to gps gnd mainboard like the picture.
Attention: if you use unprotected wire like picture, make sure it touch only gnd, not other components or you can damage phone.

Gnd require hard conductivity so
DO NOT USE VERY THIN WIRE

Where do you find the "third antenna contact"? I guess there are three and I do not want to take the second ...

What is the reason of this post? This fix is well known. A search might be helpful from time to time. The only useful info in this thread is the fact that you figured out that the other antenna is not used.

http://forum.xda-developers.com/showthread.php?t=878970

Besides yours there is also another post that does the same thing. Takes you to the first one http://forum.xda-developers.com/show....php?t=1043034

So no need for another one.

No, sorry, you're wrong.
THIS fix were not known at all! The thread you linked just refer to pull up the OTHER contact of the gps antenna, not the RUBBER ONE, which actually is the source of the problem.

So the next time please read carefully before suggesting someone a search.

This thread is VERY USEFUL! This man deserves all the praise and should be acknowledged of the REAL FINAL GPS FIX which turned my phone into what should have been since the first day!
