Which part has the radio?

---

What board or part contains the radio for the tilt? I know there are two main boards, I'm just not sure which one it is..... could it be this one?



Or is it this one?



Please let me know ^_^. I think it is the second, but just want to be sure.

Thanks,

The first one (main board). The antenna connections are on the top right on your pic.
The second board is just an accessory board for the UI (buttons, LCD connections, front cam, LEDs and memory card).
