Before springing to add Navigator to the iPhone, though, I'm wondering if anyone knows -- will your iTunes music library keep playing in the background, interrupted only for voice guidance? The version on the Pre does that, but I'd expect nothing less since the Pre's big selling point is multitasking. Does the the iPhone version do the same?

Now... AGPS chips fall into 2 categories, 1. unlocked and 2. locked. To conserve power, many cellphones use category 2 and only triangulate position from the nearest tower. Category 2 can also use verified network locations (much less accurate). Accuracy from the tower has improved a great deal over the years with the increase in speed. Inaccuracy occurs over a slow network and when your cellphone hops from one tower to the next. The triangulation (keep in mind) is based first on the tower's GPS position and then your phone. When switching to another tower on a slow network the GPS position changes but your phone's position is still roughly the same and thus you get (normally for a few seconds) a drastically inaccurate positioning.

I could be wrong but I was under the impression that the iPhone 3GS had an unlocked AGPS chip... weak but still able to communicate directly with GPS satellites. Regardless... TomTom has stated that their iPhone hardware will contain its own GPS chip to augment the iPhone's for a much more accurate and quick positioning par with a standalone GPS unit.

My only concern with ATT Navigator is the volume. I can just barely hear it with the speaker held right up against my ear! And I'm not going to drag a cable out to connect my iPhone to AUX... I shouldn't have to, especially for $10 per month! I should put on a pair of headphones while using Navigator... then when I get pulled over, foot the bill over to ATT. That would not only offset my $10 service, but probably my entire phone bill!

Clearing the decks for iPhone mania!! 

I got me all over the place, quickly and accurately, the whole time I was there. My trip took me from the city, almost to the Canadian border, and places in between. I'd turn this on any time I needed to get around somewhere I didn't know.

Then Navigon came out, and I tried it. A few days after purchasing, I requested and received a refund from the AppStore. It's awful at doing the basics, and the screen is plastered with floating, outdated, POI icons that can't be shut off.

Between the 2, AT&T Navigator is the clear option...

BTW, on the forums, after the post with this review, I have a review of Navigon. I then do a quick compare of both of them.

yea, there is a little trick you can do with safari to make a bookmark that'll jump you to the end of the page: http://ipuhelin.com/en/safariplus/

@jbrandonf I will cordially disagree , I really like there isn't a "read more" link, I want the whole thing to read, I hate having to click on something to continue reading in my "reader".

Speaking of which, does anyone know if you can jump to the bottom of the iPhone screen for a webpage? You can jump to the top, but bottom? That would be a good feature for long articles.

In Google Reader i wanted to quickly open this in a new tab and then keep browsing my feeds but I had to scroll a shitload just to get to the bottom of the feed to open it in a new page. I'm asking to just add a 'Continue reading this post' or something after the first couple paragraphs or so.
