Iphone is powered by, surprisingly, a Samsung processor, not Intel. While standard or even mobile Intel processors would be able to power the graphics demanded by Jobs, it probably would have readily sucked down power faster than the Samsung, so the iPhone would have had less than 5 hours of talk time.

The iPhone has to have some sort of mobile graphics chip in it, since the keynote mentioned that the phone supported Core Animation (which requires some sort hardware accelerated graphics). The animations the phone was doing in the keynote were just too silky smooth to be running without some sort of hardware acceleration.

It just has to have either an ATi Imageon or nVidia GoForce somewhere inside. Since nVidia acquired PortalPlayer, which makes the chips that drive the current iPod, I think that the GoForce is more likely, maybe a 4800 looking at nVidia’s spec sheets. Also, while the phone probably isn’t running full-on OS X, I bet a lot of the code base is there, just pared down for a mobile device, similar to how the Nokia N800 is running a scaled down Linux distro. That’s the beauty of *NIX based OSes, the ability to pare down the OS to the the bare minimum of what you need for the implementation.

FBR Research believes that the suppliers for the major components in the iPhone will be:

       1. Samsung Electronics for the CPU/Video processing
       2. Marvell for the 802.11 chipset
       3. Infineon Technologies for baseband communications
       4. Broadcomm Corp. for the touch screen controllers
       5. Cambridge Silicon Radio for the Bluetooth chipset
