I do agree the GPS on the Samsung Galaxy is poor. Sometimes it works beautifully without problems. However The satellite lockup is still slow compared to my HD2 and Nexus ( which is within few seconds). I was driving to KL one day and after I pass Sg Besi toll, I got a shock , the weather widget ( Beautiful Widgets ) shows I was in ROME !!! Geez, what a shock, after a few kilometres I see Kuala Lumpur registered on screen

And YES, if you want to use the Galaxy S better installed OCLF or Voodoo Lagfix - it boost its performance up very much

Mine unit same as yours and I have the luxury of bricking it twice !!! It is very dangerous to attempt install other firmware but I have learn from experience and sharing with you tips.

You will read that you can go into download mode using ADB reboot download - YES , you can do that but the chance of a failed installation is very high , your phone can hang and no respond. When you take out battery or disconnect USB, you will see a logo of phone disconnected with PC. No matter what you try very difficult to restart it - it is BRICKED and best choice sent in service center - they will reflash rom for you

BEST way to ensure you do not brick phone is to do this method to have phone get into DOWNLOAD mode : http://forum.xda-developers.com/showthread.php?t=785201
It is 100 % SAFE and RELIABLE

Also learning from my bricking experience, before you switch roms again, you must redo above process _ NEVER NEVER use adb reboot download method

As long as you follow this, I assure you phone will not brick.

Whether one like it or not, the lag issue is a undisputed feature of galaxy s due to it using a internal flash drive. Phone great specs but letdown by this. Can easily resolve using voodo lag fix or one click lag fix

I have posted here before saying the galaxy s without applying the lag fix is a poor performer compared to my other nexus n even hd2 on android. Having these 3 phones I can see the obvious differences how badly the galaxy s fall behind the other 2 phones. With the lag fixes is better but still loses to the other 2 phones in file access, still slow at least by 2 to 3 secs
Gps is another weak point. I rarely use it, I prefer using the hd2 android whose gps pickup is excellent within seconds and accurate.

Program launching though slower perform ok when executed.
