iPhone 3G and firmware 2.0: the day after

So many of you are probably still in your jammies, reveling in the afterglow of yesterday's purchase, repeatedly opening Maps on your glossy new iPhone 3G and watching in exaggerated wonderment as your location is determined with frightening speed and accuracy. Others might be standing in a line snaking hundreds of bodies long into your friendly local Apple Store, reading this post from the comfort of your Motorola RAZR V3 and realizing that these are some of the last moments you'll be using a physical keypad. Still others are bemused by the fuss -- but whatever your stance on the phone, it's pretty hard to ignore the buzz that's floating around in the aftermath of day zero. Here are some of the goings-on we're tracking:

• The masses of humanity continue to collect. Massive stock shortages don't seem to be an issue (yet), but patience is not a virtue we hold dear to our hearts, so we really can't blame these people.

• Some buyers are reporting a yellow tint to their screens -- probably not enough to notice without another unit side-by-side for comparison, but real nonetheless. Of course, the first iPhone suffered from the occasional crappy backlight, bum touchscreen, or negative black, so we wouldn't be surprised if a few lame displays made it out of the factory floor for this model as well; we're following up with Apple on this and we should have more for you later today.

• We took the iPhone 3G on a decent drive around New York, and found its tracking to be impeccable. In a situation where we might have veered off the path following Google Maps directions, the blue blip kept us right on track. Despite what you've read (we're looking at you, Mr. Pogue), we see no technical reason that the aGPS can't provide turn-by-turn directions, provided there's software to take advantage of it.

• There are some complaints floating around about 3G reception, but it's been just fine on our review units around the world so far. How's it treating you out in [your location here]?

• iphone-dev has a video up of BootNeuter going about its business on a first-gen iPhone that's been upgraded to firmware 2.0, and the process is looking as slick and painless as ever. Unlockers who haven't shelled out for the 3G, commence your salivating.

• MobileMe seems like it's up for the moment, but don't breathe too hard lest you bring the whole thing down again.

Update: We just spoke with Bob Borchers, senior director of product marketing for the iPhone, and he had some very interesting info regarding the "yellow screen" phenomenon we've been hearing about. According to Bob (and Apple), the screen's color temperature has been purposely altered on the new iPhone to produce warmer, more natural tones, sharper images, and deeper blacks. The company says that 1st gen iPhone screens appeared colder and less defined, and they made some adjustments for the new models. In our opinion, what he says is right on -- the screens do look better on the iPhone 3G versus the older variety. What do you guys think?
