Just wanted to let people know that GPS was a big thing for me. I use it to get to places all the time, and I like to use apps that incorporate GPS into it.
I tried everything on my first captivate. I was a rom flashing whore because so many roms promised fixes. I tried jupiter files. I tried changing LBS test mode configurations to every combination possible. All of this made my GPS slightly usable at best.
Then by almost divine intervention, I finally got GPS working on my captivate. My external speakers stopped working, so I was forced to trade my old captivate for a new one at no cost.
First thing I did was check the GPS. I heard rumors that Samsung placed a faulty GPS chip in the first generation captivates. They didn't want to announce a massive recall in fear of losing tons of money. This rumor seem to be true.
Without changing anything I now have a fully functioning GPS system on my captivate. Follows me exactly where I am without jumping around or constant recalibration. Works on Standalone without the aid of wireless networks... exactly like it should work.
My advice to anyone complaining that their GPS isn't working right on their phone, swap it. If it really bothers you...then ground yourself in and argue that your phone's GPS isn't working right and you want a new one.
Don't let ATT fool you into thinking its working by changing settings like use wireless networks. It will almost always find you immediately, especially if you're on wifi. Your GPS should be working without it, and should be on standalone instead of ms based to prevent the weird jumping around.
For those of you whose 1 year warranty is over (although I doubt that's anyone since the phone is fairly new)... tough cookies. I don't see how an update can fix a faulty GPS chip. Especially since my GPS is working great stock on the same update that I had on my phone before I swapped it.
