Apple At the D11 conference, Apple CEO Tim Cook once again took the stage to be interviewed by Walt Mossberg and Kara Swisher. While most of the interview can be replicated by picking and reading 10 random Apple fanblog stories - there were still a number of very interesting things that warrant some closer scrutiny.

"How? I can't even connect any of my Bluetooth GPSs to any iOS device.

I'm curious. Why would you want to do that? From the reviews of these kinds of apps it seems like it's only useful if your phone has crappy GPS reception. I geocache extensively, and so far my iPhone is always more accurate and faster than dedicated GPS units that other people have.
Just FYI, answering someone's question with "why would you want to do that" doesn't look good for your part of the debate. To answer though, the iPhone (and all other smartphones besides) use cel triangulation to assist the internal GPS receiver. The internal receiver on most smartphones (iPhone included) is actually pretty bad. Low accuracy, small antenna. They can make up for it by triangulating your position through your cel or data towers, and even Wi-Fi fingerprints if that area has been surveyed. If you're in an area where you don't have much reception, or there are just too many towers and Wi-Fi fingerprints to accurately find you, however, you'll notice a drastic drop in the accuracy of the internal gps receiver.
However, that being said, I have the Bad-Elf GPS Pro receiver. Connects to my iPhone over Bluetooth just fine, where as on Android I have to run a background app to pass Bluetooth gps coordinates as a mock location to Google's location APIs. There are Bluetooth GPS receivers that work with iOS, just not all of them.
