I know this post won't help you but...
I live in NYC and whenever I get 3G its a nightmare. Its as if my data completely breaks. It will show me it is connected but will not show the up and down arrows moving.
I just want to know if I'm alone out there, if I have a faulty phone or something. All in all my phone's data connection seems to only work on 1x, and when it finds 3G it is terrible and doesn't work 80% of the time, and if it does, its slower than my 1x speeds.
If there is a way to disable the 3G radio, somebody please help >_<
