Engadget has an internal memo from AT&T with a few things about the iPhone.
More info at http://www.engadgetmobile.com/2007/04/25/iphone-qanda-for-atandt-employees/
The highlights:
With an iPhone you'll have access to Cingular's MyAccount via the device as well as via iTunes.
Sorry, no pre-orders (yet).
If one wants to read tea leaves, it's still probable there will be iPhone specific service plans.
"... no subsidies are being offered on the phone at this time." You heard 'em!
They will "allow" out of contract customers to sign up for two more years to get an iPhone. Sui generis!
Where to buy the iPhone
The iPhone will be available in Cingular company-owned retail stores, at www.cingular.com, and will be offered through Cingular's direct mail/direct response channels in June 2007. The iPhone will also be available in Apple stores and at www.apple.com.
Q. If I am an existing customer, can I upgrade and will you give me an upgrade credit/subsidy for this device?
A. An existing customer can purchase the iPhone for the same price as anew customer. However, no subsidies are being offered on the phone at this time.
