I'm wondering if the iPhone is more tied to Cingular than most phones would be.
In the play-by-plays I read earlier today there was mention of Apple and Cingular working closely to launch this device.
I'm only halfway through the keynote now, but features like the voicemail access where you can access individual messages through the UI aren't features I've seen before. Steve mentioned this was a "collaboration."
Also, I heard mention that the US is getting the iPhone in June, and Japan is getting it in 2008. Did Steve say when Europe will be getting the phone?
