Hi,
I just looked up the values for power consumption @Nick Knatterton found out some time ago (
here), it says 10mA for a 603 with touchscreen active, 4,2mA with touch inactive, which would be the same for the 602 I guess. This value shouldn't drop very much with keylock on, except you don't need extrapower for the G-sensor.
Unfortunately he didn't give a value for booting, but I'll ask him, then we can calculate it by ourselves.
