Shame, such an empty thread.
Today I would like to contribute some information.
I own a GT99 for about a month. Overall I am very happy with the phone, but the GPS performance was really not good at all. I tried every software fix I could find on the Internet. Things improved a little bit but the result was still not good enough. Then, inspired by a video on You Tube I started looking on the hardware side of the story. To cut it short: Connect a approx. 10 cm long fine wire to the GPS antenna underneath the back cover and the phones GPS comes to life. No longer intermittent reception and the first fix is normally under 10 seconds now.
