Shadowmite, your picture entitled "6800-ant1.jpg", with the white part, that is what our phones actually have, correct? I completely see what you're saying by something "missing", i.e. a longish trace that goes around the similar part. However, the thing pictured in 6800-ant1.jpg, doesn't that correspond to a "Patch Antenna", that many many stand-alone GPS devices have? It looks awfully similar to the antenna found in my Garmin eTrex Legend. A quick Wiki reference pulls up this:

http://en.wikipedia.org/wiki/Patch_antenna

Maybe I'm wrong, but the fact is, it's still something. Malatesta, as you have indicated the Kaiser's gpsOne device is the same that we have - the MSM7200 is nothing more than an MSM7500 with a GSM radio and associated tx/rx infrastructure.

I have heard arguments about frequency-modulating the Wifi/BT antenna or even the radio antennas, though I don't know quite exactly how that would accomplish anything reliably - though I freely admit that my background is in digital systems and embedded software, not signals.

I guess my bottom line is this: I choose to believe that we have a hardware GPS capability in the phone, and I believe we have the antenna for it. Patch, or "frequency modulated", whatever it may be, I think we have it. I'm hopeful that we can finally have some peace about this, and that I won't have to carry around my Holux M1000 (the free pouch that came with it is a lifesaver. )... though I suspect that the high-sensitivity SiRF-III receiver on the Holux might beat the crap out of the Mogul's receiver. Either way, let's just hope for the best!
