I got my 8GB iPhone in hand at about 6:14PM on Friday. I was seventh in line at the AT&T store of about 57 people. We don't have an Apple Store here. Nobody had to camp out. First person in line was there at 9AM, I was there at noon. Three news crews came by, one came back again for a follow up. Not everyone was going to get one, the AT&T employee said that a fair number (10-15) were in a gray area. I didn't stick around to find out if they actually got one or exactly how many there were.
Activation of the iPhone was really easy on iTunes and took less than five minutes. I was not an AT&T customer and I didn't want to cancel my other service so I opted for a new number. Maybe that's why it was so fast and easy.
First, I want to say that the iPhone is a *lot* to take in at once. I watched all the videos beforehand and it still packs a bunch of features, tons of them undocumented. I'm still finding new things that it does.
The keyboard is really great. The dictionary works great and when you're trying to spell something not in the dictionary, you can hold you finger down on the keys and slide it until you get the right key. That's a great feature.
A small gripe for Mail, it does not have a spam button (at least not for Yahoo Mail, which is what I was trying.)
Safari was my main reason for getting the phone. I have to say that it does disappoint me a little tiny bit. Informationally, the web is all there. But you can only click and scroll. No double click or drag and drop, so 3rd party apps are going to really be limited on this phone.
And finally, my main gripe is that Safari sometimes adds extra space to the right of many different pages. The iChess and listingly 3rd party apps designed to fit the page have to be pinch-zoomed in order to see them even though they are only 320 pixels wide. (The page appears to be 750-1000 pixels wide by default.)
I have to say I love this phone and I can live with the couple of annoyances because this is one %&*# sweet @$# phone! Very glad I got it. If you haven't already, go buy yours *now*!
