i may have the perfect solution for this....(especially if you're operator is Tmobile)
go to start>settings>connections>connections.
manage existing modem connections.
tap and hold that connection located there and delete it.
now without connecting to a wifi signal, open your browser and type a site (ex. google.com) and if that edge/3g doesn't pop up, SUCCESS!!!
hope it works and good luck.
