When GSM on with sleep mode (or power saving but still connect to GSM
network), the GSM module will _flicking_ the power from 1-2mA to couple
uA, could observed on power supply's LCD panel. If not in power saving
mode, it will takes about 20mA at idle. But yesterday's suspend
experiment result was GSM module still takes 40-50 mA, that is way to
high. It might because some configuration issue or unknown new moko6 GSM
firmware issue.
