The kind of error that caused the GPS problem is very common in *every* new commercial product development. The severity varies, but I've been bitten by it many time.

I think the devs at OpenMoko handled this one very, very well. And, I think that most of the users handled it very, very well too. The heroes of this story are of course whomever at OpenMoko came up with and implemented the fix, but also the user in Germany who isolated the bug down to the SD card through careful testing. That is the kind of cooperation that shows the value of Free Software.

What was the time diff between the moment that the SD card was isolated as the source of the problem, and when a software fix was found, tested, and made available? Two days? One day? That's amazing. Hats off to everyone.
