For starters though, we introduce to you, the block diagram:

The Qualcomm MSM7201A, which was previously used in later US iterations of the Touch Diamond and the Touch Pro, comes full force in the G1.

Similar to the BlackBerry Storm, the GPS and audio processing components are embedded into the processor.

Fortunately, HTC has had much experience using the processor, although it runs a brand new OS.

Running alongside the processor is the transceiver and power management ICs, Qualcomm RTR5285, and Qualcomm PM7540, respectively.
