I too have been attempting to identify a fix to this issue. I was even fit to get the 3G toggle to show up in unit settings thru registry alters, but the toggle did definitely nothing, my 3G still remained on even tho the toggle declared off.I unequivocally redesigned to Mango RTM trusting conceivably for an answer, but that didn't do anything either. I even attempted the diagnositc codes and altering the indicator, but still nothing. It's the one situation that positively bugs me concerning this telephone! Should have the ability to turn off 3G!So if any individual spots a result, im paying attention!
