Forcing 3g?

[colonelcack]

Sometimes when I'm in areas where I have 1 bar of 3g it'll go back and forth between 1x and 3g. When I was on tmobile I was able to resolve this by using anycut and making a shortcut to activites>phone info. From there you can select your prefered network type...but I can't seem to figure out which one is forced 3G for virgin, it was different on tmobile. I thought it would be CDMA only but it still goes back and forth between 1x and 3g sometimes. Anyone know which one to use to do this?
