A little history about Samsung, and not just phones. Have a Samsung Blu Ray player, 2nd to last firmware release broke it and 3 months went by before they addressed the problem. In the meantime, they pulled the defective firmware and replaced it with the previous one as well as a document stating for your to rollback as a workaround. Only problem was, you can't rollback, so that generated a second wave of complaints.
The same can be said with the Galaxy S, people forget that this line has been around almost 6 months now. Started back in Asia then Europe then the US. You would think by now they would know how to solve the GPS problem and have Froyo available for carrier consumption. It's not like they can't get Froyo while in development, same as Microsoft does with software companies.
As for the Captivate fix, ex-Captivate owner here, it was a total sham. The GPS issue was not fixed and some of the other improvements were not noticeable. To make matters worse, the initial AT&T documentation did not state that a GPS fix was included. Only after it was released, did both parties claim that was the case. 2 days after the release, I called AT&T which in turn conferenced in Samsung support to discuss my GPS issue. Not only did I not get an answer, the Samsung techs we spoke with on that call had different stories and no clue what the firmware version they just released was.
In summary, Samsung might have a product with great possibilities but they don't know how to deliver such possibilities. Not only have they lost me as a cell phone customer, I won't buy a single product from them. Just recently, someone I know bought another product that claim to have certain capabilities only to find out that was not the case after calling Samsung. My recommendation to those of you within 30 days, return the phone. I went past my 30 days telling myself all was going to be alright and Samsung would deliver, three months later, it was a total disappointment.
Spending $200 to be a Samsung crash test dummy is not worth it, your money is better spent somewhere else. I miss the 4" display, the live wallpapers, the notifications of the Android OS but at least my IPhone4 can find me when I decided to use the GPS and without any delay. It's a shame, I would have loved to keep my Captivate and continue to use Android. But thanks to Samsung, that experience was ruined and there was no other alternative with AT&T that I could have used to continue it.
