I would like to share a GPS Antenna Hardware Hack i found here "http://www.androidpit.de/de/android/forum/thread/435065/HTC-Desire-HD-Hast-du-GPS-Probleme-mit-deinem-DHD"into the internet some time ago.
I tryed allot of fixing apps and software modifications but nothing works realy good for daily work with gps so i started to soldering a cable (0,8mm) to the GPS Antenna contacts (have a look to the picture)
after the assembly and a new start I had after 10sec sat-fix from 5-6 satellites in the room!!!
Outside I have sat-fix within 2 sec
Here some steps how to do, but be carefull you will lose the warranty of your device
1. open the device like in the youtube video described (http://www.youtube.com/watch?v=7qm_z65LA8k)
2. solder a cable to the antenna contacts like the picture shows
3. assembly the device ... reboot and have fun
