Prop, for your knowledge-
100% wrong.
Some phone triangulate towers to show location. iphones can triangulate if you have a signal OR lock in to satellites just like a standalone gps. I have a full detailed map of us & canada including waypoints, POI's etc, INSTALLED on my device. No type of data connection is required whatsoever.
In early august I was in the northwoods with my phone capabilities turned OFF to conserve battery (so as to not continually search for signal)and compared GPS results to my handheld Garmin 60cxs.
Accuracy was very near equal, with the garmin being a little faster to lock in and movement. Map detail and info was far superior on the iPhone software I have installed.
The GPS chip of iPhone 3G and 3GS is an Infineon PMB 2525 Hammerhead II chip with -160 dbm.
The Garmin 205-305-405 chip is the Sirft Star III with -159 dbm.
The iPhone's GPS slightly better than popular Garmins, however since it has a much smaller antenna and it's stuffed in there with a #g radio, wi-fi, bluetooth, etc. performance is slightly affected.
Like I said, I've had many and I find the iPhone far superior to all. In regards to buisness, the only thing my BB could do that this couldn't, is make/receive phone calls via wi-fi without the use of an outside program. That was a great feature. I don't know why AT&T will allow that on the BB & not the iPhone. I've found ways to make many other things work, but not that yet.
I too am just looking to make sure the correct information is out there & yours was very inaccurate.
The user has a lot to do with it. I've shown other iPhone users my phone compared to theirs, and it's night & day. I will say it didn't come out of the box comprable to the others, but thats what I like about it, far more versatile for tweaking to what you want it to do than any other, kinda like my sled.
