Whew!! I almost forgot to cover the 2 most important questions.
Where can i buy it? AND How much does it cost?
And even though there's been plenty of rumors. It will ONLY BE AVAILABLE through CINGULAR/AT&T. For now at least. Verizon and TMobile will have it down the road.
It will be available at all Cingular and Apple stores, kiosk's and online.
Apple authorized resellers will not be allowed to sell the new iPhone
(The supposed iPhone killer is also in the works)
