It is very misleading, as the results of this "fix" (or the many permutations thereof) are by no means proven by any statistical definition of the word.
Lots of people seem to think that allowing use of cell/wifi to get a very rough static location is also "fixing" the GPS location problem (it is usually good enough for location services other than navigation, after all), and GPS reception is a very variable thing, so even one person proving a fix "worked" for them is difficult, much less proving it really works for a substantial number of people. It could simply be the reboot that makes things better for many.
I've tested all the LbsTestMode options claimed to be successful and more; some help momentarily, some make things worse.
But what it really comes down to is this : No matter how long it may take to get a lock, even with no other location assist, all 10 other GPS devices I've had in the past 15 years can keep the lock once acquired *far* better than the Captivate. Especially when in a moving vehicle, just putting the Captivate on my lap causes it to lose reception on a crystal clear day with my convertible top down. My old LG Incite and a BlueTooth GPS receiver and a Garmin and a Mio all hold the signal no problem on my lap, sometimes even under my seat.
There is a GPS reception problem with the Captivate that is deeper than anything the LbsTestMode settings can address, though perhaps some of them can make things appear slightly better for static GPS location.
It is a shame, because it is a great phone, but mine is going back because I have not been able to get any convincing evidence from Samsung that a *real* fix is even possible, much less truly arriving in September as they state. I suspect they are just hoping we get caught up in all the froyo goodness and so tolerate the deficient GPS.
I'll pay the $35 restocking fee, wait to hear some convincing evidence that the GPS issue is really fixed with the upcoming September "fix," and then get one that is fixed (or wait for the next great Android device if it isn't really fixed).
