Disable EVDO, Why? B/c of Sprint Airave.. Help?

[tntsniper]

I have the Airave and it uses 1x, but the diamond wont go outta EVDO until I dial out or I do something.. If someone calls me it'll finally hit at one point to the Airave service, but thats every blue moon.

I found out that if I disconnect the data and reconnect it'll hit 1x instead of EVDO..

So I was wondering if anyone had made a program or hack or something that could switch my EVDO off and on when I want

Thanks!
