This 1-2mA figure must be bogus and caused by low bandwidth in the
ammeter.  1-2mA is not enough to either make problems for the LED
regulator nor to actually run the radio in the GSM stuff.

Well that much is probably no worse than other phones since it runs the
receiver in there.

Wah it takes double in suspend than from active.  It's calling some bad
sex phone line when it thinks we don't know!
