That [EMAIL PROTECTED] doesn't cut power to the modem. Instead, it tells the modem to "power down", i.e., to enter its own standby mode, from which it can be awakened by "pressing" the modem's "on" button. (That "button" is in fact a transistor controlled by MODEM_ON line which connect to the CPU's GPB7.) What does cut power to most of the GSM chipset is the GSM_ON line which connects to the PMU's GPIO2. Alas, the modem's RF amplifier is not controlled by this (it doesn't like anything to get between it and the battery), so the GSM subsystem cannot be entirely cut off. - Werner
