UPDATE 2: After spending a few hours with the new iPhone, I'd say it's another winner. I'm not 100% sure it's a must-have upgrade if you're already using an iPhone 3GS, but after I've spend some more time with it, I should have a better idea. The screen is as beautiful as expected and text is remarkably crisp. Using the two cameras is a snap and setting the phone up is familiar and quick.
The earlier report of yellowish spots on the screen is apparently a byproduct of the manufacturing process and will go away in a day or two, but the reception issues seem to be persisting (though I can't reproduce the problem on my phone).
I'll be posting more impressions of the phone later tonight, as well as some articles about the new HD camera and features of the OS.
UPDATE: after four hours of waiting, I've got the iPhone 4 in my hand and in my house. Just about to set it up and the posts from me will start flying. More soon.
The iPhone 4 is on sale the world over and lines are long. The Providence Place mall in my town, Providence, RI, had easily 500 people when the Apple store opened at 7 a.m. today. Lines elsewhere in the world are likely even longer. I'm about to leave the keyboard and go get in line. More on the release of the phone as it transpires and I have connectivity.
In the meantime, bug reports are trickling in from new iPhone 4 owners, including:
It remains to be seen whether these are isolated problems or signs of larger issues.
