But a receiver isn't neccessarily a discrete chip. My AT&T Tilt has an
on-board "real" GPS, but the Qualcomm GPS chipset is built into the
processor chip itself. Remember the "I" in IC is for "Integrated!"
It's quite likely the GPS chipset is built-into the Apple-silkscreened ARM
processor that runs the phone.
As to the antenna, I can't help you- maybe the foam-covered hunk of copper
and what's under it over by the SIM slot (at the J2 connector?) Beats me-
I'm a layman.
I've seen a disassembly of MY phone:
http://www.pdacenter.ru/razborka/razbor_htc_kaiser (it seems safe to browse,
but I don't blame you for not rushing out and trying a .ru link suggested by
a stranger!) and I couldn't find one in the low-res watermarked pics, but
admittedly I was looking for the typical square-wafer ceramic type GPS
antenna I'm used to seeing in a GPS. Who knows what HTC actually uses to
save space in an already crowded device? A piece of tin-foil tape cut to
length?
It's fun to bash Apple amidst all the hype, I guess, but I believe them when
say a GPS is on board. If it wasn't, and just a cellular/WiFi-based
simulation was being used, I'd expect Apple to tell the world they were
"adding GPS" to the older iPhones as well, but they seem to be making a
distinction vs. the "less accurate" positioning in the original iPhone, and
the "more accurate" positioning in the new iPhone 3G. That could only be
adequately explained by a real GPS.
I should be easy enough to figure out- perhaps an iPhone 3G user could run
the Google Maps app, get their location, then turn off the WiFi and GSM
radios then walk/drive around a bit to see if the dot moves? I assume the
Google Maps application would still work without a data connection, using
the GPS, for a little while, at least until it attempts to fetch a new map!
But, not to drift TOO far off topic, do you really have nothing better to do
at 7AM than harrass/"educate" customers standing in line to buy a product?
Did you hangout at CompUSA pestering the three or four people queued up when
Vista was released, extolling the virutes of Linux? ;-)
No GPS?
