I actually find this to be intermittent, sometimes it fails, sometimes it works.
I also tried disabling and rebooting, and it worked fine ( ie. 3g was still disabled ).
When it comes back and reports that 3g is still enabled, ofono's RadioSettings 'TechnologyPreference' property is set to "any", as opposed to "gsm". Looking at the ofono rilmodem radio-settings code this shouldn't happen. This *may* be an ofono bug, but can't tell without more testing.
