After the first hour or so of playing w/ different OS images, the exposed RF-shield (under the battery cover) gets quite hot. I'm was pretty sure this shield only covered the EG25, so flipped the modem kill-switch to off. It's still getting quite hot... so I've got two questions (one of which I can probably answer from the schematics):
1) Does the RF-shield act as a heat-sink for both the modem *and* the SOC?
2) What does the modem kill-switch actually do to the modem? Place in reset? Physically remove power?
EDIT: Took a me a bit to realize that the symbol for the killswitches is split through-out. SW1-A is the 2-pins for the modem kill-switch, and looks like it is intended to cut power at the Q1500 power mosfet. Has anyone confirmed that the EG25 does not draw unwanted power when disabled?
