I had something strange happen to me yesterday. I have the elite and my wife has the ov. I had noticed slow internet speeds on my elite the last couple of days so I ran speednet test and had 130kbps downloads. My wife's ov was over 2000(with mirage's ROM).
So even though my status bar showed 3g , in : settings: about phone: status: the network showed 'CDMA- 1x-rtt'.
I tried every thing,I went to ##DATA# no luck. Long story short, I had to run the activate app to get my 3g back.
Don't know if that helps anyone or not but don't always trust the 3g symbol in status bar.
