   Regardless of Telit/UART or Option/USB, we need to answer a question:
How do we wake up from suspend on incoming call/SMS? Remember that the
Calypso couldn't do that out of the box, it needed a firmware modification.

   The lack of USB busses could perhaps be solved by including a USB hub. We
ought to have some room to spare with the removal of the Glamo, NOR flash,
audio amplifier. If we can live with the power consumption of a USB hub, it
would solve the Option 3G vs. Bluetooth conflict and still have two USB
ports that could be useful for hardware hacks.
