I have 2.2 and it seems to work
I have an app called GPS Test (It cannot start GPS on its own).
Tried test again.
..Made sure GPS was unchecked.
..Went to the website and started a locate.
..Minute later, the website located my phone correctly.
..GPS Test was green and showing several satellites it was receiving data from.
..Stopped the location process.
..GPS Test then determined GPS was now shut off..
It somehow is turning the GPS receiver on and off remotely.
