Our work Sprint Blackberry Curve 8530's are having huge issues with the 1XEV network. The town we operate in has a week 3G signal, but a strong 1X signal. On my Bold 9700, I can lock the phone to 2G if I want, but I don't see that option on the 8530.
We're dropping calls and the phone switches frequently between 1X and 1XEV.
