Some people are reporting that their GPS is working, while some are saying it's failing. We know the software on all the Captivates is the same, but it's conceivable that some units came from batches that had hardware defects. Therefore, a hardware defect, or at best variance, is more likely to be the cause. This could mean one of two things: Either the problem is not fixable as a result of it being a hardware issue, or it's fixable if the said hardware issue could be compensated for somehow by special treatment from the software. It's not likely that there's software variability.
