Walt Mossberg has everything you need to know about the new iPhone and iPhone software.
Update: The find my iPhone feature (with iPhone 3.0 and a MobileMe account) is pretty freakin’ cool. You sign-on to MobileMe from any browser, send your phone a banner message (like call me at such-and-such hotel), an optional signal that will sound on the phone even if the phone is locked (so the cab driver hears it from the back seat), and there’s an option to delete your data from the phone.
My sister and I have ours reserved (a white 16GB 3Gs for her, a black 32GB 3Gs for me), and we’re heading to the Apple Store at 7 a.m. tomorrow to pick them up (we hope). We’d have preordered, but since my mom has a 3G we all figured we’d just get on a family plan.
Gizmodo has a nice review matrix for the 3Gs up:
