I didn't check Giz today, there is some
more info out now, albeit its AT&T specific. You'll probably still need to wait until its out to find out what's really going to happen.
People are already talking about the next iPhone.
There are rumours about the next iPhone in 2010... It might have the new Atom processor. Think of that.... A phone that's got the computing power of a 1.6ghz Celeron
